A shear creep test was performed for weak intercalation in order to investigate influence of creep characteristics of weak intercalation on slope stability. The obtained curve from the test was fitted according to Cvisc creep constitutive model, and the creep of slope with weak intercalation was calculated by using finite difference method to analyze the variation in long-term displacement and shear strain increment of the slope. The results show that the weak intercalation has typical creep characteristics. The results obtained from the numerical calculation with Cvisc model are basically consistent with the actual monitoring data. The creep characteristics of weak intercalation cause not only increase in the displacement, but also significant changes in the distribution form and orientation of the overall displacement of the slope, especially greater displacement at the top and in the middle of the slope. As a result, the slope body experiences an increment in the shear strain, which is then expanded and finally tends to stable.

通过软弱夹层剪切蠕变试验,探究软弱夹层蠕变特性对边坡稳定性的影响,根据Cvisc蠕变本构模型拟合试验曲线,并采用有限差分数值计算方法对含软弱夹层边坡进行蠕变计算,分析了边坡长期位移和剪应变增量的变化。结果表明,软弱夹层具有典型的蠕变特性;采用Cvisc模型进行数值计算得到的结果较符合实际监测数据;软弱夹层的蠕变特性不仅使位移量值增加,也使边坡整体位移分布形式和方向发生显著变化,且坡顶和坡中位移值较大;坡体剪应变增量经历了出现、扩展到趋于稳定的过程。

通过软弱夹层剪切蠕变试验,探究软弱夹层蠕变特性对边坡稳定性的影响,根据Cvisc蠕变本构模型拟合试验曲线,并采用有限差分数值计算方法对含软弱夹层边坡进行蠕变计算,分析了边坡长期位移和剪应变增量的变化。结果表明,软弱夹层具有典型的蠕变特性;采用Cvisc模型进行数值计算得到的结果较符合实际监测数据;软弱夹层的蠕变特性不仅使位移量值增加,也使边坡整体位移分布形式和方向发生显著变化,且坡顶和坡中位移值较大;坡体剪应变增量经历了出现、扩展到趋于稳定的过程。

A shear creep test was performed for weak intercalation in order to investigate influence of creep characteristics of weak intercalation on slope stability. The obtained curve from the test was fitted according to Cvisc creep constitutive model, and the creep of slope with weak intercalation was calculated by using finite difference method to analyze the variation in long-term displacement and shear strain increment of the slope. The results show that the weak intercalation has typical creep characteristics. The results obtained from the numerical calculation with Cvisc model are basically consistent with the actual monitoring data. The creep characteristics of weak intercalation cause not only increase in the displacement, but also significant changes in the distribution form and orientation of the overall displacement of the slope, especially greater displacement at the top and in the middle of the slope. As a result, the slope body experiences an increment in the shear strain, which is then expanded and finally tends to stable.
