摘要
国道219线隆子县金东乡段改建工程滑坡威胁着在建国道、过往行人及车辆的安全。通过实地勘察了解滑坡工程特性及灾害发育史,借助数值模拟软件FLAC3D,选取滑坡A区作为典型面,模拟分析了该区的稳定性,进而确定安全系数,为后期的工程治理提供相应的依据,也为西藏高海拔地区类似该滑坡的研究提供一定的参考。
The landslide in the reconstruction project of Jindong Township section of Longzi County of national highway 219 threatens the safety of pedestrians and vehicles on Jianguo Road.Through field investigation,this paper understands the engineering characteristics and disaster development history of landslide,selects landslide area a as a typical surface with the help of numerical simulation software FLAC3D,simulates and analyzes the stability of this area,and then determines the safety factor,which not only provides corresponding basis for later engineering treatment,but also provides some reference for the research of similar landslide in high-altitude areas of Tibet.
