摘　　要：以某高速公路堑坡顺层滑坡为研究对象,通过野外调查和物探钻探,对该滑坡的工程地质条件、水文地质条件、边坡开挖方案等方面进行了研究。通过地勘资料和现场调研获取该滑坡的土体材料强度参数,采用UDEC对其施工期稳定性开展模拟分析,探讨开挖效应对边坡的影响。研究为随后该边坡的处置设计提供了参考。Taking a bedding landslide along a cutting slope of an expressway as the research object,the engineering geological conditions,hydrogeological conditions,and slope excavation schemes of the landslide were studied through field investigation and geophysical drilling.The soil material strength parameters of the landslide were obtained through geological survey data and on-site investigations.UDEC carried out a simulation analysis of its stability during the construction period to explore the influence of excavation effects on the slope.The research provided reference for the subsequent disposal design of the slope.
