| 摘 要： | 水对边坡的失稳有很大的影响,在内蒙古西部干旱地区,往往由于集中降雨导致大量的路堑边坡失稳破坏,本文分析了降雨对边坡的不利影响,提出了考虑降雨作用的边坡稳定分析方法,并通过工程实例对该地区的边坡稳定性进行数值分析计算,其方法对干旱地区的路堑边坡设计及稳定性评价具有重要的借鉴意义.

| Abstract: | Rainfall in the western part of Inner Mongolia Autonomous Region is very rare. In this area, the limited rainfalls usually concentrate in a short period, which sometimes cause the instability of highway slope. The instability mechanism of highway slope caused by rainfalls in arid area is discussed；and the analysis method for slope stability evaluation is suggested. A practical case study is carried out by using the proposed theory and FE method. The method proposed can be for reference in researching and designing highway slopes in similar area. |
