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 shortcomings of the current research on landslide stability evaluation, this paper uses the method of satellite real-time monitoring to analyze the stability of the landslide using the law of surface displacement. This method has the advantages of stable and intuitive monitoring method and real-time and reliable analysis results. Taking Duzhaiping landslide in Dujiangyan City, Sichuan Province as the research object, the surface deformation of the Ta Zhaping landslide is analyzed based on the deformation law of the displacement-time curve of the landslide body and the on-site monitoring data so as to divide the deformation stages of the landslide body. The comparison between the data before landslide reinforcement and the landslide body demonstrates that the landslide body gravity retaining wall treatment method is feasible and concludes that the landslide body has been stabilized after being treated.
