摘　　要：滑坡是山西省山区较常见的危害较大的地质灾害之一。只有正确认识和分析滑坡的阻滑情况,确定滑坡阻滑段位置,才能更好的制定相应的防治措施,避免或减轻滑坡地质灾害的发生。文章以清徐县李家楼滑坡作为研究对象,利用现场开挖探槽及稳定性计算等方法,对滑坡前缘阻滑段阻滑情况进行分析,得出滑坡阻滑翘起段对于滑坡的稳定性起到了至关重要的作用,为滑坡治理工程的布设提供基础资料,亦为相似工程提供一定的参考。Landslide is one of the most common geological hazards in mountainous areas of our province.Only by correctly recognizing and analyzing the situation of landslide and determining the location of landslide sliding section,can the corresponding prevention and control measures be better formulated to avoid or mitigate the impact of landslide geological hazards.Taking the Lijialou landslide in Qingxu county as the research object,landslide resistance is analyzed in the front of the landslide by excavating grooves and calculating its stability.It can be concluded that anti-slip upwarping section plays a crucial role in the stability of landslide.It provides basic information for the layout of landslide control projects and some references for similar projects.
