清江古树包滑坡滑带土的Mesri蠕变模型

Mesri's Creep Model for Qingjiang Landslide-Zone Soil

通过对清江古树包滑坡滑带土进行室内流变试验,将试验结果进行分析,引入Mesri模型,采 用Singh Mitchell应变速率 时间关系方程来描述土体的蠕变特性,得出了该土的蠕变型式.该模 型的参数少且适用性强.

The indoor creep tests for the Qingjiang Gushubao landslide-zone soils have been carried out;and some creep data are obtained.Analyzing these creep data,and adopting Mesri Model and the Singh-Mitchell's strain rate-time function to study the creep of this soil,the creep type of soil is obtained.There are only few parameters in this formula are needed to determinate.It is easy to use and feasible for engineering practice.
