摘要： 滑坡是一种常见的不良地质现象，对工程安全危害较大。结合某高速铁路DK121+525～+665段坡积粉质黏土坡体滑坡病害，对其成因进行了全面分析；结合病害成因、地质条件、验算资料等，采用刷方减载、抗滑桩、系统截排水等综合治理方案。治理完成经过二年的雨季及运营检验，坡体现状稳定，治理效果良好。

Abstract: Landslide is a common geological hazard and it might potentially pose a significant threat to the safety of engineered structures. This paper presents a case history of a landslide hazard between a high speed rail stations DK 121+525 and +665. The mechanism, subsurface geotechnical conditions and backcalculation results of this silty clayey soil landslide are also discussed in the paper. The mitigation measures are: unloading, antislide caissons, and drainage installation. The two years operation after the mitigation indicates these measures are successful.
