摘要
以西攀高速公路K151＋180-650m深挖路堑开挖失稳形成昔格达层内滑坡为例，总结了昔格达组泥岩与砂岩互层半成岩堑坡的工程地质特征，分析了开挖、场区构造影响和水文地质条件对堑坡失稳的影响，以及开挖造成部分坡体沿层面失稳的机理。并对失稳堑坡提出了综合治理措施，以及堑坡开挖失稳的防止对策。
Based on the researching on K151 ＋ 180 - 650 m landslide along the Xi - Pan Expressway the paper described the geologic characteristic ; analyzed the infection of the excavating, the structure and hydrogeology conditions of the slope, and summarized the slip mechanism on the landslide of the approximately level excavated slope in Xigeda Formation. The advanced control strategy is provided.
