摘　　要：联补水电站施工过程中,左岸山体崩坡积层出现裂缝.通过对地表裂缝发育特征的分析,发现裂缝均为拉张性质,表现出典型的土体蠕变特征,各部位裂缝成因略有差别.通过地表以及深层变形监测数据分析,并采用离散元模拟左岸山体斜坡变形失稳的全过程等,提出了左岸山体整体稳定、无明显的整体变形破坏迹象的重要结论,为工程设计及枢纽安全运行提供了依据.The colluvium of left bank hilly region cracked in the construction of Lianbu Hydropower Station, which are proved be tension Cracks because of different reasons in different regions based on the analysis on crack growth of earth surface. The paper draws the conclusion that there is no deforming phenomenon as a whole in left bank hilly region after analysing the monitoring data of surface and underground deformation by gliding simulation on discrete mode.
