With the slopes of an open-pit mine in Inner Mongolia as the research background, the creep characteristics of soft rock in the slopes were investigated by means of field monitoring, laboratory test and theoretical analysis. Real-time monitoring results of the slopes from radar and GNSS found that the creep deformation is relatively larger on the eastern side of the northern slope, which requires key protection. When the axial stress exceeds the long-term strength, the soft rock goes through four deformation stages:instantaneous deformation, decelerating creep, steady-state creep and accelerated creep. Creep deformation and creep rate of soft rock are positively correlated with axial stress. A nonlinear creep model for slope soft rock is established by combining elastic elements, fractional-order element and nonlinear viscoplastic body (NVPB). This model can well describe the whole creep process of slope soft rock, with higher fitting accuracy than that of traditional Burgers model, and also demonstrate favorable applicability.

以内蒙古某露天矿边坡为研究背景,通过现场监测、室内试验和理论分析相结合的方法,对边坡软岩蠕变特性进行了研究。边坡雷达与GNSS实时监测系统发现,边坡北帮东侧蠕变变形较大,需重点防护。当轴向应力超过长期强度时,软岩表现出瞬时变形、衰减蠕变、等速蠕变和加速蠕变特征。软岩蠕变变形和蠕变速率与轴向应力呈正相关关系。将弹性元件、分数阶元件和非线性黏塑性体进行组合,建立了边坡软岩非线性蠕变模型,该模型能较好地描述边坡软岩的蠕变全过程,拟合度高于传统Burgers模型,适用性良好。

以内蒙古某露天矿边坡为研究背景,通过现场监测、室内试验和理论分析相结合的方法,对边坡软岩蠕变特性进行了研究。边坡雷达与GNSS实时监测系统发现,边坡北帮东侧蠕变变形较大,需重点防护。当轴向应力超过长期强度时,软岩表现出瞬时变形、衰减蠕变、等速蠕变和加速蠕变特征。软岩蠕变变形和蠕变速率与轴向应力呈正相关关系。将弹性元件、分数阶元件和非线性黏塑性体进行组合,建立了边坡软岩非线性蠕变模型,该模型能较好地描述边坡软岩的蠕变全过程,拟合度高于传统Burgers模型,适用性良好。

With the slopes of an open-pit mine in Inner Mongolia as the research background, the creep characteristics of soft rock in the slopes were investigated by means of field monitoring, laboratory test and theoretical analysis. Real-time monitoring results of the slopes from radar and GNSS found that the creep deformation is relatively larger on the eastern side of the northern slope, which requires key protection. When the axial stress exceeds the long-term strength, the soft rock goes through four deformation stages:instantaneous deformation, decelerating creep, steady-state creep and accelerated creep. Creep deformation and creep rate of soft rock are positively correlated with axial stress. A nonlinear creep model for slope soft rock is established by combining elastic elements, fractional-order element and nonlinear viscoplastic body (NVPB). This model can well describe the whole creep process of slope soft rock, with higher fitting accuracy than that of traditional Burgers model, and also demonstrate favorable applicability.
