摘要

云南是中国滑坡灾害最严重的地区之一。在高速公路的建设过程中，出现了许多滑坡的稳定性问题。分析滑坡稳定性的关键是获得较为准确的滑动面力学参数。首先提出了滑坡滑动面力学参数分析的内容以及主要的研究方法，然后针对云南一高速公路玄武岩滑坡的滑体松散、取样困难的实际情况，采用现场试验的方法进行滑动面力学参数分析，并采用基于稳健回归分析的计算方法进行滑动面力学参数的计算，能有效地减少异常值的影响，从而获得更为可靠的滑动面力学参数。同时指出，古滑坡滑动面的抗剪强度的分析应考虑时间效应下残余强度的恢复。

Abstract

There are many landslide disasters in Yunnan Province of China. Many problems of landslide stability occur during the course of constructing highways in Yunnan Province too. It is proved to be crucial in the analyses of landslides stability to obtain the more exact parameters of slip surface. Firstly

the content and the main research method of the parameter analysis of slip surface are held up. Secondly

when the stability of basalt landslide on a highway in Yunnan Province is analyzed; in-site test are adopted to obtain the parameters of slip surface

because sliding mass of basalt landslide are loosen and sampling is difficult. Lastly

the robust regression analysis method is used to deal with the test data and calculate on the parameters of slip surface. Compared with other routine methods

the robust regression analysis method can reduce availably the effect of abnormal value

and then the results are more credible. Furthermore

it is pointed out that the restorations of residual shear strength on time effect are considered on analysis of the parameters of the fossil landslide slip surface.
