Abstract

Abstract: This paper presents evaluation of the slope stability in loess soils in a mountain highway project in west Henan Province by using unsaturated soil mechanics theory. Based on the laboratory tested mechanical and physical properties of loess soils and tested soilwater characteristics curve, potential affecting factors for the loess slope stability, such as, ratio of slope, height of slope and climate, are numerically investigated for the effect of moisture content and pore pressure fields. The loess slope stability analysis results under various working conditions are also provided.

Key words: unsaturated soils, loess slopes, slope stability, laboratory tests
