摘　　要：永安中学古滑坡位于通江右岸,为发育于缓倾角顺层砂泥岩互层结构中的蠕滑-拉裂型滑坡。按坡体结构及地下水和人类工程活动的差异将滑坡分为3个区进行分析;根据滑坡各区的坡体结构、坡面形态、堆积体成分及变形破裂状况,分析滑坡复活体成因机制;定性计算滑坡各区的稳定性,在选用抗滑桩支挡与排水工程相结合的整治措施后,采用数值计算的手段研究了抗滑桩的有效布设位置,建议在复活体中部设桩对滑坡进行治理。The landslide lies in the right bank of the Yong＇an tongkiang. It developed in slow angle. It is creep and cracking landslide in mudstone layer structure. According to the structure and the slope of groundwater and human engineering activities, it is divided into three landslide zone to be analyzed. According to the structure of landslide slope, slope surface morphology, composition of accumulation body and deformation and fracture, the resurrection mechanism is analyzed. The stability of landslide districts is calculated. After selecting the combination of anti-slide pile retaining and drainage engi- neering of control measures, the effective pile location was calculated by numerical calculation. Finally the paper suggested that the piles should be located in the central resurrection body.
