The stability analysis of expansive slope in Jing-Yi Expressway

摘要

This paper firstly introduces the distribution of weathered layers, and then presents the relationship between water content and expansive force and the working model of expansive forces in expansive soil slopes. Taking the expansive soil slope of Jing-Yi Expressway as example and applying the Slices Method, this paper puts forward the stability calculation method considering the effect of expansive forces, and also proposes the treatments.
