摘　　要：针对山西某滑坡的边界条件、形态特征、结构特征、变形趋势,根据该滑坡体垂向上大致分为第四系全新统和上更新统、石炭系中统本溪组和上统太原组、奥陶系中统马家沟组等三层,前缘由于长年遭受河水冲刷,使滑坡体前缘临空,滑坡是由土体的自重、其上加载、各种动力作用、前缘临空、降雨和地下水等因素影响而形成,按变形阶段该滑坡处于蠕滑变形拉裂阶段,变形破坏形式为滑坡体沿底部基岩产生蠕滑,经过滑坡变形宏观分析、滑坡变形监测、滑坡稳定性计算及处置方案探讨,提出整体搬迁避让方案.According to some landslides＇ boundary conditions, morphological characteristics, structural features, deformation trend of Shanxi, and based on the landslides body vertical, it is roughly divided into quaternary system Holocene series and Upper Carboniferous in the Benxi group and the upper Jurassic Taiyuan formation, Middle Ordovician Majiagou group. Fronts have suffered from rivers. It leads to the landslides front overhead, and landslides are formed by the soil weight, its load, various dynamic effects, leading overhead, rainfall （rainstorm or long-term rainfall） and the influencing factors of groundwater etc. According to the deformation, the landslides are in the stage of creep deformation crack stage, deformation and failure form of creep landslide body along the bottom of bedrock. This paper provides the overall relocation project after the landslides deformation macroscopical analysis, landslide deformation monitoring, macro analysis of stability calculation and disposal methods of landslides.
