边坡稳定性分析一直是岩土工程中重要的研究课题,在岩土工程或土木工程领域占据相当重要的地位。滑坡是一种严重的岩土体失稳现象,降雨原因引起的滑坡称为降雨型滑坡。以丹东至通化高速公路滑坡体的稳定分析为例,根据该地区工程地质特点,采用了折线滑动法,并在此基础上考虑水的作用力。结果证实了降雨(尤其是大量的降雨或暴雨)无疑是触发滑坡的最主要的因素之一。
Slope stability analysis has been an important research topic in geotechnical engineering, occupying a very important position in the field of geotechnical engineering or civil engineering. Landslide is a serious phenomenon of rock and soil instability. The landslide caused by rainfall is called rainfall-type landslide. Taking the stability analysis of landslide body from Dandong to Tonghua Expressway as an example, according to the engineering geological features in this area, the polyline sliding method is adopted, and based on this, the water force is considered. The results confirm that rainfall, especially heavy rainfall or heavy rainfall, is undoubtedly one of the most important factors triggering landslides.
