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.

Key words: arid area, highway slope, rainfall, stability analysis, FEM
