摘要

摘要: 利用重力压密原理制样, 采用陈氏加载法, 对某大型滑坡滑带土剪切流变特性进行研究。选择伯格粘弹性本构模型描述滑带土的流变性状, 获得了滑带土的长期强度值, 并论述了长期强度在滑坡稳定性研究中的意义。

Abstract: The shear rheologic behaviors of soil in slip zone of a large-scale landslide are studied in this paper. The samples are prepared in accordence with the gravity compaction principles and by Chen Zonglis the loading method. The rheologic behaviors of soil in slip zone are described by the Burgers visco-elastic Model. From the test results, the long-term strength parameters are obtained, and its significance in study of the stability of landslide is also discussed.
