摘　　要：膨胀土具有显著的胀缩性、多裂隙性和超固结性,膨胀土质的路堑边坡常因坡体含水状态的改变而产生各种病害。通过对膨胀土的物理力学参数及其工程特性进行分析,总结了膨胀土路堑边坡的破坏形式及机理,在此基础上提出了几种适用于膨胀土路堑边坡的防护措施,可为实际工程提供借鉴。Expansive soil has such remarkable characteristics as expansibility, multi-fissure and over-consolidation. Changes of water content in the expansive soil slopes often lead to some engineering disasters. Based on the analysis of expansive soil＇s physical and mechanical parameters and its engineering properties, this paper summarizes expansive soil slope＇s failure modes and mechanisms, then puts forward some applicable measures for expansive soil slope protection, which will offer some reference for practical engineering.
