摘　　要：黄土广泛分布于我国中西部,随着"西部大开发"战略实施,中西部基础设施建设不可避免遇到大量黄土高边坡,而黄土高边坡变形破坏机理是其预测预报的基础及防治设计的依据。文中将铁路沿线黄土高边坡分为六类地质结构模型,分析其变形破坏的类型、特点、机理及其危害,并提出了防治建议。Loess is widely distributed in mid-west region of China.With the implementation of ＂Western Development＂ strategy,infrastructure construction in mid-west region will inevitably encounter a large amount of high loess slopes.While the deformation failure mechanism of high loess slopes is the basis for its prediction and prevention.This paper classifies high loess slopes along the railway into six types of geological structural model to separately analyze the failure type,characteristics,mechanism and disaster and put forward suggestions on prevention.
