摘　　要：攀西地区昔格达地层在开挖时极易形成滑坡灾害,威胁工程建设工人的安全。以某高速公路典型昔格达地层的挖方边坡变形、破坏后形成滑坡为例,分析典型昔格达地层滑坡的变形机制,梳理昔格达地层发生滑坡的关键影响因素,总结处治昔格达地层滑坡问题的关键要点,为昔格达地层挖方边坡的工程建设提供参考。The Xigeda stratum in Panxi region is very easy to form landslide disaster during excavation,which threatens the safety of engineering construction workers.Taking the landslide formed after the deformation and damage of the excavated slope of a typical Xigeda stratum of an expressway as an example,the deformation mechanism of the landslide in the typical Xigeda stratum is analyzed,the key influencing factors of the landslide in the Xigeda stratum are sorted out,and the key points of treating the landslide in the Xigeda stratum are summarized,which provide references for the engineering construction of excavation slopes in the Xigeda stratum.
