摘　　要：天水市秦州区北山地质条件复杂,地质灾害发育强烈。芦家湾滑坡位于天水市北山中梁乡北侧,滑坡体呈长舌状,长840m,宽210m,体积约136×104m3,属大型黄土滑坡。滑动方向105°,滑体坡度10°～35°。1979年发生滑动,导致芦家湾整村搬迁。本文通过现场调查,充分分析滑坡的工程地质条件,对芦家湾滑坡的稳定性进行了定性与定量评价,以定性分析为主,并借助多种计算手段该滑坡进行了稳定性分析,得到关于芦家湾滑坡稳定性分析定量化的评价结果。The conditional of geological is complicated and geological disaster development strongly in Tianshuishi Beishan.Lujiawan landslide located on the north side of Zhongliangxiang in Tianshuishi,the landslide is a long tongue,long 840m,wide 210m,about the size of 136×104m3,genus of large loess landslide.Slip direction 105°,slope gradient of 10°~35.Slide in 1979,led to the relocation of the village Lujiawan.Based on the careful field-work and qualitative analysis,this paper presents a series of calculation method and corresponding assessment result about stability analysis of Lujiawan landslide.
