摘　　要：滑坡灾害严重影响人类生产生活,滑坡稳定性分析对滑坡灾害发展趋势及治理至关重要。根据西安航天基地南侧滑坡成因、形态、物质组成等特征,定性、定量评价滑坡的稳定性。研究表明:定性分析认为1层滑坡处于蠕动变形阶段,稳定性定量计算认为1层滑坡在自重、暴雨及地震三种工况下,处于欠稳定~不稳定状态;2层滑坡在天然状态(自重工况)下及遭遇暴雨天气(自重+暴雨工况)下,处于稳定状态,在地震工况下均处于欠稳定状态。提出了防水工程、支挡工程和监测工程等防治方案建议,为研究区滑坡灾害治理提供了科学依据。Landslide disaster seriously affects human production and life. Landslide stability analysis is very important for the development trend and treatment of landslide disaster. According to the characteristics of landslide genesis, morphology and material composition in the south of Xi′an Aerospace base, the stability of landslide is evaluated qualitatively and quantitatively. The research shows that the qualitative analysis shows that the first layer landslide is in the creep deformation stage. Quantitative calculation of stability considers that the 1-story landslide is in less stable to unstable state under three conditions of self-weight, torrential rain and earthquake. The 2-story landslide is in a stable state in the natural state(self-weight condition) and in heavy rain weather(self-weight + heavy rain condition), and is in a less stable state under earthquake conditions. Proposals for prevention and control schemes such as waterproofing engineering, supporting engineering and monitoring engineering are put forward, which provides a scientific basis for landslide disaster management in the study area.
