摘　　要：成都东部高台地丘陵地区广泛分布的粘土层,膨胀性突出。本文结合该区内某铁路路堑边坡实例,分析边坡变形产生的原因及其变形破坏的发展趋势,提出了边坡工程的整治方案,总结了该膨胀土边坡变形整治的经验。The expansivity of the clay layer which widely distributed in hilly area of high tableland in eastern area of Chengdu is outstanding.This paper took a railway cutting slope in this area as an example to analyze the reasons for deformation occureing in the slope and the development trend of deformation,proposed the regulation project for the slope engineering,and summed up the experience of regulation deformation in slope of expansive soil.
