| 摘 要： | INTRODUCTION Jing-Yi Expressway (95 km) is the Jingmen-Yichang section of the Hangzhou-Lanzhou Ex-pressway line. The embedment slopes along the lineare mainly expansive slopes causing many incon-veniences for engineering. With longtime exposure,water accumulated in widespread sections because ofbad drainage measures, and constructions collapsed.In this work, a selected representative sector’s stabil-ity is analyzed and the corresponding reinforcementmeasures are presented.

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