摘　　要：文中首先对膨胀土路堑边坡滑坡规律以及失稳成因进行了研究,从膨胀土路堑边坡变形和破坏的特点出发,并根据地质力学模型建立起符合实际情况的膨胀土路堑边坡计算模型,对模型参数取值的方法进行了讨论,并用FLAC进行数值模拟来验证所采取的支挡措施是否合理。This paper first develops studies on rules of expansion soil slope slide and reasons for the unsteadiness, then starting from the characteristics of expansion soil slope deformation and damage it establishes expansion soil slope calculation model that accords with actual situation on the basis of geologic mechanics model. This paper also deals with discussion on the way of selecting model parameters and verifies if the support measure is reasonable by the way of FLAC.
