To ensure the structural safety of the double row steel sheet pile cofferdam and control its water use area, the single-factor sensitivity analysis method was carried out to study the impact of various items on the deformation of cofferdam, and the PLAXIS software was used to implement the 2D and 3D finite element calculation. The results show that the elevation and tension of tie rod, and the specification of steel sheet pile have little impact on the deformation of cofferdam in soil; Compared with the width of the cofferdam itself, the deformation of cofferdam is more affected by the width of inner foot, so the width of the inner foot should be increased as much as possible; The depth of the outer sheet pile has no obvious impact on the deformation of the cofferdam, so that it can be reduced appropriately, and the depth of the inner sheet pile can be increased; The effect of the transverse structure on controlling the deformation of the cofferdam is not obvious, and other measures can be taken to strengthen the connection between the inner and outer sheet pile. The research ideas and calculation results can provide reference for structural design optimization of steel cofferdam in similar projects.

为保证双排钢板桩围堰的结构安全并控制其用水面积,采用单因素敏感性分析方法研究了多项设计参数对围堰变形的影响,并通过PLAXIS软件进行二维、三维有限元模型计算。结果表明,拉杆标高、拉杆张紧力、钢板桩抗弯刚度对围堰入土段变形的影响较小;与堰体自身宽度相比,围堰变形受到内侧压脚宽度的影响更大,应尽量增加内侧压脚宽度;外侧板桩入土深度对围堰变形无明显影响,可适当减小外侧板桩入土深度、增加内侧板桩入土深度;横隔结构对控制堰体变形的效果不明显,可采取其他措施以加强内外板桩连接。研究思路和计算结果可为类似工程钢围堰结构设计优化提供参考。

为保证双排钢板桩围堰的结构安全并控制其用水面积,采用单因素敏感性分析方法研究了多项设计参数对围堰变形的影响,并通过PLAXIS软件进行二维、三维有限元模型计算。结果表明,拉杆标高、拉杆张紧力、钢板桩抗弯刚度对围堰入土段变形的影响较小;与堰体自身宽度相比,围堰变形受到内侧压脚宽度的影响更大,应尽量增加内侧压脚宽度;外侧板桩入土深度对围堰变形无明显影响,可适当减小外侧板桩入土深度、增加内侧板桩入土深度;横隔结构对控制堰体变形的效果不明显,可采取其他措施以加强内外板桩连接。研究思路和计算结果可为类似工程钢围堰结构设计优化提供参考。

To ensure the structural safety of the double row steel sheet pile cofferdam and control its water use area, the single-factor sensitivity analysis method was carried out to study the impact of various items on the deformation of cofferdam, and the PLAXIS software was used to implement the 2D and 3D finite element calculation. The results show that the elevation and tension of tie rod, and the specification of steel sheet pile have little impact on the deformation of cofferdam in soil; Compared with the width of the cofferdam itself, the deformation of cofferdam is more affected by the width of inner foot, so the width of the inner foot should be increased as much as possible; The depth of the outer sheet pile has no obvious impact on the deformation of the cofferdam, so that it can be reduced appropriately, and the depth of the inner sheet pile can be increased; The effect of the transverse structure on controlling the deformation of the cofferdam is not obvious, and other measures can be taken to strengthen the connection between the inner and outer sheet pile. The research ideas and calculation results can provide reference for structural design optimization of steel cofferdam in similar projects.
