摘要： 对益湛线K331+320～+600左侧路堑边坡的现场滑动变形破坏特征进行了分析描述，阐述了产生滑动变形的主要原因，利用工程地质分析法和滑坡传递系数法综合评定，表明滑坡现状条件下不稳定，必须对滑坡进行整治，建议采用支挡为主截排地表水和疏排地下水为辅的综合整治措施。针对工程特点，强调在滑坡整治过程中，应加强对边坡岩土体的取样和测试工作，根据岩土体工程地质条件动态设计，做到既经济又安全。

Abstract: A landslide occurred at a cut slope left side of YiyangZhanjiang Rail Line between Station K331+332 and +600. This paper characterizes the factors that might contribute to the sliding. The condition of the current slope is analyzed by the engineering geology and landslide transfer methods. It is concluded that the current slope is instable and mitigation is necessary. The remediation scheme is focused on a new retaining structure, diverting the surface runoff water as well as providing proper drainage to the groundwater. During the design, proper sampling and testing work are necessary in order to quantify the engineering properties of surrounding soil and rock materials.
