| 摘 要： | 滑带土强度参数的正确选取是滑坡稳定性评价和抗滑工程设计中的关键问题。在已有研究成果的基础上，以四川薛城镇滑坡为例，对其滑带土样进行固结–大位移环剪–再固结–再环剪的剪切试验，再现复活型滑坡滑带土的强度特性，提出基于不同有效垂直应力(滑动体覆盖厚度)采用相应的残余强度和再生强度参数的取值方法，并论证其合理性，对复活型滑坡滑面强度参数的合理取值具有极为重要的参考价值。

| Abstract: | The strength parameters of sliding zone soil are indispensable factors for stability evaluation and countermeasure design for landslides.Based on the previous study results,the shear tests on sliding zone soil derived from Xuecheng landslide,located along Zagunao river,Sichuan province,are conducted as follows:first the sliding zone soil is consolidated;then large displacement ring sheared,then consolidated again,and last ring sheared again;and the strength characteristics of sliding zone soil of the reacti... |
