To investigate the deformation mechanism of underground electrical conduits in soft soil considering the softening effect under traffic loads, a USDFLD subroutine was developed based on the dynamic modulus attenuation model. This subroutine was imported into ABAQUS software to establish a three-dimensional finite element model of electrical conduits buried in soft soil foundations. The finite element method was used to analyze the dynamic response of underground electrical conduits under traffic loads. The effects of different traffic load magnitudes (${50}\%$full load,100% full load,200% overload,300% overload) and burial depths (800,850,900,950mm)on the mechanical properties of electrical conduits were studied. The results show that the softening effect of soft soil has a significant impact on the dynamic response of electrical conduits under traffic loads. As the traffic load magnitude increases, the settlement of the electrical conduit gradually increases, and the strain at the bottom of the conduit shifts from symmetric to asymmetric distribution, with an increase in the strain concentration area. Increasing the burial depth of the electrical conduit can significantly reduce the impact of traffic loads on the conduit. When the burial depth increases from${800}\mathrm{\;{mm}}$to${950}\mathrm{\;{mm}}$, the vertical displacement decreases by${39}\%$. The research results provide a scientific basis for the design and construction of power pipes in soft soil areas, and help optimize the depth of pipe embedding and cope with the influence of different traffic loads.

为了研究交通荷载作用下考虑软土软化效应的电力排管变形机理,基于动弹性模量衰减模型,编写USDFLD 子程序,并将该子程序导入 ABAQUS软件中,建立软土地基中埋置电力排管的三维有限元模型,采用有限元方法对地下电力排管在交通荷载作用下的动力响应进行分析,研究不同交通荷载大小(满载 50%、满载 100%、超载 200%、超载 300%、 超载 300%)、埋置深度(800、850、900、950mm)对电力排管力学特性的影响。结果表明:软土的软化效应对电力排管在受交通荷载作用下的动力响应有显著影响;随着交通荷载大小的增加,电力排管的沉降逐渐增大,排管底部的应变从对称分布转向不对称分布,应变集中区域增加;增大电力排管的埋深可以显著降低交通荷载对排管的影响,当埋置深度从${800}\mathrm{\;{mm}}$增加至${950}\mathrm{\;{mm}}$,竖向位移减小39%。研究成果为软土地区的电力排管设计和施工提供科学依据,帮助优化排管埋置深度和应对不同交通荷载的影响。

为了研究交通荷载作用下考虑软土软化效应的电力排管变形机理,基于动弹性模量衰减模型,编写USDFLD 子程序,并将该子程序导入 ABAQUS软件中,建立软土地基中埋置电力排管的三维有限元模型,采用有限元方法对地下电力排管在交通荷载作用下的动力响应进行分析,研究不同交通荷载大小(满载 50%、满载 100%、超载 200%、超载 300%、 超载 300%)、埋置深度(800、850、900、950mm)对电力排管力学特性的影响。结果表明:软土的软化效应对电力排管在受交通荷载作用下的动力响应有显著影响;随着交通荷载大小的增加,电力排管的沉降逐渐增大,排管底部的应变从对称分布转向不对称分布,应变集中区域增加;增大电力排管的埋深可以显著降低交通荷载对排管的影响,当埋置深度从${800}\mathrm{\;{mm}}$增加至${950}\mathrm{\;{mm}}$,竖向位移减小39%。研究成果为软土地区的电力排管设计和施工提供科学依据,帮助优化排管埋置深度和应对不同交通荷载的影响。

To investigate the deformation mechanism of underground electrical conduits in soft soil considering the softening effect under traffic loads, a USDFLD subroutine was developed based on the dynamic modulus attenuation model. This subroutine was imported into ABAQUS software to establish a three-dimensional finite element model of electrical conduits buried in soft soil foundations. The finite element method was used to analyze the dynamic response of underground electrical conduits under traffic loads. The effects of different traffic load magnitudes (${50}\%$full load,100% full load,200% overload,300% overload) and burial depths (800,850,900,950mm)on the mechanical properties of electrical conduits were studied. The results show that the softening effect of soft soil has a significant impact on the dynamic response of electrical conduits under traffic loads. As the traffic load magnitude increases, the settlement of the electrical conduit gradually increases, and the strain at the bottom of the conduit shifts from symmetric to asymmetric distribution, with an increase in the strain concentration area. Increasing the burial depth of the electrical conduit can significantly reduce the impact of traffic loads on the conduit. When the burial depth increases from${800}\mathrm{\;{mm}}$to${950}\mathrm{\;{mm}}$, the vertical displacement decreases by${39}\%$. The research results provide a scientific basis for the design and construction of power pipes in soft soil areas, and help optimize the depth of pipe embedding and cope with the influence of different traffic loads.

电力管线是城市基础设施的重要组成部分, 是城市安全高效运行的“生命线”, 任何轻微的损坏都可能导致严重的安全隐患[1]。近年来,直埋电缆敷设方式逐渐被排管敷设方式替代, 其中上海中心城区的地下电缆化率已超过${80}\%{}^{\left\lbrack 2\right\rbrack }$。随着城市交通与运输业的快速发展, 由交通荷载引起的地下电力排管破损问题也逐渐加剧, 进而导致城市断电等风险,因此交通荷载对电力排管的扰动影响研究是维护电力安全的重要课题。
当前货运量急剧增加,重型、超重型车辆层出不穷, 因此地下管道受交通荷载作用时的变形性能和力学响应受到广泛的研究。Alzabeebee 等[3] 研究了地下管道受静态和移动交通载荷下的影响。肖成志等[4] 针对地下管道开展了静载和循环荷载试验,分析了不同因素对管道变形机理以及管周土压力分布规律的影响。Mehrjardi 等[5] 研究了在土工格室和橡胶- 土体混合物制备的沟槽中管道受循环载荷作用下的行为。Huang 等[6] 研究了埋地钢管在车辆和飞机等多重荷载作用下的力学行为。王丽萍等[7] 对承插式球墨铸铁供水管道开展了竖向荷载作用下的破损试验和数值模拟。Robert 等[8] 使用综合现场仪器对直径${660}\mathrm{\;{mm}}$ 的铸铁管进行了现场埋管的性能监测。Zhou 等[9] 研究了埋在纯土和橡胶-土混合物中管道的动力响应。李玉坤等[10] 建立车-管-土耦合模型,分析了车辆荷载作用下埋地管道的动力响应, 得到不同时刻埋地管道的应力分布规律。
软土地基具有高孔隙比、高压缩性、低抗剪强度等特性, 在交通荷载作用下, 其强度会发生衰减, 对地下结构造成显著影响。Cheuk 等[11] 研究了软黏土海床上管道动态铺设过程及小振幅振动下的管道力学特性。吴奇等[12] 对扰动海洋原状土的不排水剪切强度及剪切波速的相关性进行了系统分析。慕东霖等[13] 研究了考虑软土应变软化效应下的桩头位移-反力响应与桩身截面弯矩的发展规律。吴宜鹏等[14] 在基于 Tresca 屈服准则的理想弹塑性模型中引入软土强度随着塑性应变累积的衰减规律, 进而对软土中深埋式大圆筒结构的水平承载力特性进行了系统的数值分析。徐林荣等[15] 提出不同因素影响的软土累积塑性应变模型, 并以此模型为基础进行了交通荷载诱发的软土地基长期沉降计算。程星磊等[16] 研究了一种可描述循环荷载作用下饱和软土软化特性的增量弹塑性模型。孙苗苗等[17] 通过空心扭剪试验研究了不同因素下原状软黏土软化指数和累积塑性应变的关系。
虽然软土地基受交通荷载作用的影响已受到一些研究关注, 但是对于埋置在软土地基中的电力排管受交通荷载作用下的动力响应特性的研究较少。鉴于此, 基于动弹性模量衰减公式编写 USDFLD子程序, 通过考虑软土软化效应和混凝土动力损伤特性, 建立软土-电力排管结构非线性动力相互作用的有限元模型, 分析软化效应、交通荷载大小、埋置深度对电力排管力学特性的影响。为软土地区的电力排管设计和施工提供科学依据,帮助优化排管埋置深度和应对不同交通荷载的影响。
采用 ABAQUS 来计算软土地基中电力排管的动力响应。为尽可能增大模型尺寸以减小边界效应的影响,模型整体尺寸确定为${10}\mathrm{\;m}$ (长)$\times 6\mathrm{\;m}$ (宽)$\times 5\mathrm{\;m}$ (高)。路面由面层和软土地基组成,其中面层厚度为${0.2}\mathrm{\;m}$。电力排管、垫层、路基均采用$\mathrm{C}3\mathrm{D}8\mathrm{R}$ 实体结构单元,对电力排管及交通荷载作用区域进行网格加密, 最终建立的网格数量为 53285 个,几何模型如图1 所示。
路基路面模型分为面层和软土路基两部分, 其中面层采用线弹性模型来模拟。软土地基采用线弹性模型模拟弹性性质, 用扩展的 Drucker-Prager 模型模拟塑性特性, 各层参数如表1 所示。软土地基受交通荷载长期作用下会产生应变软化现象,刘飞禹等[18] 通过考虑超固结比和偏移应力的影响提出了动弹性模量衰减公式。为考虑交通荷载作用下软土的软化特性,采用文献 [18] 中的${E}_{\mathrm{d}}- {\varepsilon }_{\mathrm{d}}$ 关系曲线进行数值模拟, 其函数形式为
${E}_{\mathrm{d}}= \left({{5.9401}+ {0.0265}{\sigma }_{\mathrm{s}}}\right)\left({-{0.0804}{\mathrm{{OCR}}}^{2}+ }\right.\\{0.7425}\mathrm{{OCR}}+ {0.3175})\times \\{\varepsilon }_{\mathrm{d}}^{\left(-{0.746}+ {0.0057}{\sigma }_{\mathrm{s}}\right)}\left({{0.02190}{\mathrm{{CR}}}^{2}- {0.18370}\mathrm{{CR}}+ {1.154}}\right)$
式 (1) 中:${E}_{\mathrm{d}}$ 为动弹性模量;${\sigma }_{\mathrm{s}}$ 为初始偏移应力,定义为初始主应力差的大小,取${40}\mathrm{{kPa}};\mathrm{{OCR}}$ 为超固结比,取$2;{\varepsilon }_{\mathrm{d}}$ 为动应变。
以 9 孔典型电力排管为研究对象, 排管与垫层计算模型如图2 所示。其中,电力排管尺寸为$6\mathrm{\;m}$ (长)$\times {0.72}\mathrm{\;m}$ (宽)$\times {0.74}\mathrm{\;m}$ (高),管孔内径为${0.15}\mathrm{\;m}$,垫层尺寸为$6\mathrm{\;m}\left(\text{长}\right)\times {1.02}\mathrm{\;m}$ (宽)$\times$ ${0.1}\mathrm{\;m}$ (高)。电力排管和垫层选取$\mathrm{C}{30}$ 混凝土,弹性模量为${30}\mathrm{{GPa}}$,泊松比为 0.27。混凝土在受循环荷载作用下会产生拉伸损伤和压缩损伤,从而导致刚度的退化。因此为精确获得电力排管的动力响应特性,采用混凝土损伤模型(CDP)模拟。CDP 模型可以较好地描述混凝土非弹性行为, 将损伤弹性与拉伸和压缩塑性相结合,适用于模拟混凝土在循环荷载作用下的破坏情况, 材料屈服后应力-应变如表2 所示。其中非弹性应变和损伤因子根据材料应力-应变曲线进行计算[19],计算公式为
${\varepsilon }_{\text{in }}= \varepsilon -\frac{\sigma }{E}$
$ d = 1 -\sqrt{\frac{\sigma }{E\varepsilon }}$
式 (3) 中:${\varepsilon }_{\text{in }}$ 为非弹性应变;$\sigma$ 为应力;$\varepsilon$ 为应变;$E$ 为弹性模量;$d$ 为损伤因子。
在本次研究中, 交通荷载作用模拟成正弦激振荷载,压力均匀分布在接触面上,接触面积为${2.25}\mathrm{\;m}\times {1.02}\mathrm{\;m}$。为了模拟不同强度的交通荷载,采用荷载幅值为${0.35}\text{、}{0.7}\text{、}{1.4}\text{、}{2.1}\mathrm{{MPa}}$,分别代表满载 50%、满载 100%、超载 200%、超载 300% 的交通情况。通过应力控制对路面进行循环加载,加载频率为$1\mathrm{\;{Hz}}$,加载次数为 200 次,具体的荷载形式如式为
$ F\left(t\right)= {Q}_{0}+ {A}_{0}\sin \omega \left({t -{t}_{0}}\right)$
式 (4) 中:$F\left(t\right)$ 为路面承受的实际荷载;${Q}_{0}$ 为车辆自身静载;${A}_{0}$ 为车辆附加动荷载;$\omega$ 为圆频率;$t$ 为加载时间;${t}_{0}$ 为初始时间。
ABAQUS 能够检测模型中的每个接触对, 界面相互作用采用面对面接触的方法。由于电力排管的刚度高于土体的刚度, 因此将电力排管的表面定义为接触对中的主面。参考 Elshesheny 等[20] 的研究, 创建非线性接触属性为法向行为和切向行为, 模型的切向行为采用库伦摩擦模型来模拟土与电力排管之间的摩擦,摩擦系数取为 0.26。法向行为采用硬接触,允许接触分离。
图3 为排管沉降随循环次数增加的变化曲线, 可以看出, 无论是否考虑软化效应, 电力排管的竖向位移在加载初期均呈现缓慢增长趋势。随着荷载作用次数增加,排管位移的增长速度明显加快, 这与 Alotaibi 等[21] 所观察到的现象一致。在满载 100% 和超载 200% 的情况下, 无论是否考虑土体软化, 排管竖向位移的增长速率在初期基本一致, 但在 75 次循环后, 考虑土体软化的排管竖向位移的增长速率明显高于不考虑土体软化的情况。这主要是随着循环次数的增加, 土体动弹性模量减小, 从而降低了土体受交通荷载作用后抵抗变形的能力。在交通荷载循环 200 次后, 考虑软土的软化效应下受超载 200% 和满载 100% 情况时,排管竖向永久位移分别为${38.9}\mathrm{\;{mm}}$${20.8}\mathrm{\;{mm}}$,两者的位移差值为${18.1}\mathrm{\;{mm}}$。比较软化与不软化的情况,这一值增加了 53.5%,因此软土的软化效应对管道受交通荷载下的沉降影响显著。
图4 为荷载作用中心下的地基土竖向动应力分布情况。交通荷载制作用下竖向应力在面层处衰减较快,面层底部竖向应力分别为 499.9、540.3 、${808.3}\text{、}{860.4}\mathrm{{kPa}}$。在软土地基区域,排管上方的竖向应力随深度先增加后减小,考虑软化情况下竖向应力的增加较大。相较于未考虑软化效应的情况, 考虑软化效应情况下作用于排管顶部的竖向应力较大,可见交通荷载在考虑软化效应情况下作用与排管上方的竖向应力更大。
图5 为排管底部轴向应变分布云图,可以看出管顶的应变分布不均匀,考虑软土软化效应与否对管底应变分布的影响较大。在不考虑土体软化的情况下,距排管中心${275}\mathrm{\;{mm}}$ 范围内的排管底部轴向应变值较小,随着距离的增大,管道底部的应变值先迅速增大,然后逐渐减小。这主要是混凝土排管底部受拉应力控制, 在管道底部中心处由于拉伸损伤系数的显著提高, 导致在底部出现多条应变集中区域。从应变云图(图5) 中可以看出, 混凝土底部的最大应变主要集中在管道中心两侧。当考虑土体软化效应时, 排管底部的最大应变值明显大于不考虑软化的情况, 相比不考虑软化时, 增大了 1.3 倍。同时, 管道底部应变集中处的应变差值也明显增加, 达到 0.0018, 是不考虑软化时的 1.2 倍。
图6 为排管底部的拉伸损伤分布云图,可以看出,最大损伤值从中心位置开始,逐渐向两侧扩展。在不考虑土体软化效应的情况下, 排管底部的塑性损伤发展区域较小,仅限于距离管底${80}\mathrm{\;{mm}}$ 范围内, 最大损伤值为 0.804。在考虑土体软化效应情况下, 排管底部的塑性损伤发展区域明显增大, 底部正中心区域增长至${480}\mathrm{\;{mm}}$ 处,并向两侧扩展,最大拉伸损伤值为 0.928 ,相较于不考虑土体软化的情况增大了 13.3%。图7 比较了考虑与不考虑软化效应下的排管拉伸损伤与压缩损伤,可以看出考虑土体软化效应后的电力排管底部受交通荷载的影响较大,管道顶部受交通荷载的影响较小。同时管道受交通荷载过程中,管道的拉伸损伤明显大于压缩损伤,因此在对危险区域进行加固时可以着重于拉伸裂缝的处理。
图8 为不同交通荷载作用下的电力排管沉降时程曲线, 随着交通荷载的增大, 排管沉降值增加。在循环 200 次后的最大沉降值从${13.52}\mathrm{\;{mm}}$ 增大至${48}\mathrm{\;{mm}}$,其中不同荷载值下的沉降值分别增大了${7.28}\text{、}{11.2}\text{、}{16}\mathrm{\;{mm}}$。这是由于随着循环次数的增加, 在较大的交通荷载情况下排管产生较大的拉、 压塑性应变,局部区域的损伤系数不断增大,进而导致电力排管的弹性刚度下降,竖向位移和变形速率也随着循环次数的增加越来越大。
图9 为不同交通荷载作用下的排管底部轴向应变曲线,应变值在管底呈现中间大两边小的分布, 随着交通荷载的增大,排管底部的应变值显著增加。当交通荷载为满载 50% 时,应变值较小,最大应变值仅为 0.00155 ,且应变值在中间区域分布较为均匀,应变集中现象不明显。当交通荷载为满载 100% 时,最大应变值增加至 0.004 18 , 距中心点${425}\mathrm{\;{mm}}$。同时,排管底部的应变呈对称分布,有 4 处明显的应变集中区域,最大应变差值为 0.00215。当交通荷载为超载 200% 时, 排管底部的应变值继续增大, 呈非对称分布, 并有八处应变集中区域, 最大应变差值为 0.003 23, 是满载 100% 情况下的 1.5 倍。当交通荷载为超载 300% 时, 排管底部的最大应变值达到 0.01187 , 有八处应变集中区域, 最大应变差值为 0.003 58, 是满载 100% 情况下的 1.67 倍。
如前所述, 电力排管在加载过程中承受显著的拉伸应变, 因此图10 对不同交通荷载下管道底部的拉伸损伤分布进行比较。由图10 可知, 拉伸损伤系数主要集中在中心区域,两侧最小,满载 50% 时的最大拉伸损伤系数为 0.814, 满载 100% 时的最大拉伸损伤系数为 0.928,超载 200% 和超载 300% 时的最大拉伸损伤系数都为 0.979 。同时, 高损伤系数区域并未均匀分布在管道中心, 而是在中心点附近存在较低损伤系数的区域, 这主要是垫层的保护, 使得底部中心处并未全部达到最大损伤系数。
图11 为满载 100% 作用下的排管断面塑性应变分布云图。可以看出, 排管的塑性应变从上往下逐渐增大, 排管底部两侧存在明显的高应变区域。在孔洞附近,竖直方向上的塑性应变明显小于水平方向上的塑性应变。这主要是由于当交通荷载作用于地面时, 土体的变形会影响到管道, 特别是管道侧面会向水平方向变形并与土体发生挤压。因此, 在交通荷载多次作用后, 孔洞的水平方向会产生较高的塑性应变。
图12 为不同交通荷载作用下正中心的排管孔洞塑性应变分布, 可以看出, 塑性应变在孔洞顶部和底部较小, 并向两侧逐渐增大。当交通荷载从满载 50% 增加至满载 100% 时, 管周环向塑性应变增加较少,最大塑性应变为满载 50% 的 2.74 倍。当交通荷载达到超载 200% 和超载 300% 时, 排管的管孔环向塑性应变增加显著, 最大塑性应变分别达到满载 50% 的 7.17 倍、10.1 倍。
图13 为满载 100% 情况下不同电力排管埋深的沉降时程曲线, 可以看出, 随着埋深的增加, 相同循环次数下的沉降量减少。在埋深${800}\mathrm{\;{mm}}$ 情况下,最大排管竖向位移为${28.7}\mathrm{\;{mm}}$,相较于埋深${850}\text{、}{900}\text{、}{950}\mathrm{\;{mm}}$ 的情况分别增加了${13}\%\text{、}{27.5}\%$、 39.1%。这表明增加埋深可以有效降低地下埋管的沉降。
图14 为不同排管埋深下的排管底部轴向应变曲线, 可以看出, 随着排管埋设深度的增加, 排管底部最大应变值减小。当埋设深度为${950}\mathrm{\;{mm}}$ 时,应变较小,最大应变值仅为 0.001 65,在距中心点${525}\mathrm{\;{mm}}$ 范围内,共有 5 处应变集中现象。当埋设深度为${900}\mathrm{\;{mm}}$ 时,最大应变增加至 0.004 18,且出现应变集中现象的区域扩大至距离中心点${1023}\mathrm{\;{mm}}$ 处。当埋设深度为${850}\mathrm{\;{mm}}$ 时,排管底部应变值继续增大,且应变集中处的应变差值明显增大,并存在八处应变集中区域, 最大应变差值为 0.00247, 是埋设深度${950}\mathrm{\;{mm}}$ 的 3.9 倍。当埋设深度为${800}\mathrm{\;{mm}}$ 时, 排管底部最大应变达到 0.00834, 存在 9 处应变集中区域, 最大应变差值为 0.00327, 是埋设深度${950}\mathrm{\;{mm}}$ 的 5.1 倍。同时随着电力排管埋深的增加, 应变集中区域的宽度增加。尽管电力排管埋深改变, 管底应变基本保持对称分布, 并未出现超载时的非对称分布。
图15 为不同排管埋设深度下的底部拉伸损伤分布云图。可以看出, 拉伸损伤系数主要集中在中心区域,在两侧最小,埋深${800}\mathrm{\;{mm}}$ 时的最大拉伸损伤系数为 0.979,埋深${850}\mathrm{\;{mm}}$ 时的最大拉伸损伤系数为 0.975,埋深${900}\mathrm{\;{mm}}$ 和埋深${950}\mathrm{\;{mm}}$ 时的最大拉伸损伤系数分别为 0.928 和 0.852。
图16 为不同埋设深度下正中心的排管孔洞塑性应变分布,可以看出,塑性应变在孔洞顶部和底部较小,并向两侧逐渐增大。当埋设深度从${950}\mathrm{\;{mm}}$ 减小至${900}\mathrm{\;{mm}}$ 时,管周环向塑性应变增加较少,最大塑性应变为埋设深度${950}\mathrm{\;{mm}}$ 的 2.22 倍。当埋设深度达到${850}\mathrm{\;{mm}}$${800}\mathrm{\;{mm}}$ 时,排管的管孔环向塑性应变增加显著, 最大塑性应变分别达到埋设深度${950}\mathrm{\;{mm}}$ 的 3.0 倍、4.64倍。
(1)软土的软化效应对电力排管受交通荷载作用下的沉降有显著影响。考虑土体软化效应后,电力排管底部的拉伸损伤明显增加, 而管道顶部受交通荷载的影响较小。
(2)随着交通荷载增加,电力排管的沉降值与沉降速率显著增大,排管底部的应变由对称分布转为不对称分布, 应变集中区域增多。排管孔洞的塑性应变在腰部位置较大,在顶部和底部较小,最大应变值随交通荷载的增大而增大。
(3)增加电力排管的埋深可以显著降低交通荷载对排管的影响,当埋置深度从${800}\mathrm{\;{mm}}$ 增加至${950}\mathrm{\;{mm}}$,电力排管的沉降值减少了 39%。
