摘　　要：针对目前滑坡稳定性评价研究的不足,该文采用卫星实时监测的方法,利用表面位移规律对滑坡体进行稳定性分析,此种方法具有监测方法稳定直观、分析结果实时可靠的优势。以四川省都江堰市塔子坪滑坡为研究对象,依据滑坡体表面位移-时间曲线的变形规律,结合实地监测数据对塔子坪滑坡的表面位移规律进行分析,从而划分滑坡体的各变形阶段;通过与滑坡体加固前的数据相对比,论证了滑坡体重力挡墙治理方法的可行性,并得出了治理后的滑坡体目前已趋于稳定状态的结论。Aiming at the insufficiency of the evaluation study on the landslide stability, the paper a- dopted the method of satellite real-time monitoring to analyze the landslide stability with the law of surface displacement, which has the advantages of stable and intuitive monitoring method and real-time and relia- ble analysis results. Taking the Taziping landslide in Dujiangyan city of Sichuan province as the study ob- ject, based on the deformation law of displacement-time curve of landslide surface, it analyzed the surface displacement rule combined with field monitoring data, and divided the deformation stages for the land- slide; then compared with data before the landslide reinforcement, proved the feasibility of the landslide gravity retaining wall governance approach; finally concluded that the landslide mass after the governance had been in a stable state.
