摘要
在勘察监测川黔铁路 K119裁缝岩滑坡的基础上，阐述了该滑坡的基本特征和形成机制，运用 Bishop 法，计算了该边坡的稳定性，得到该边坡的稳定性系数，并采用 FLAC3D软件，对该边坡的破坏机制进行了数值模拟分析，结果表明，采用 Bishop 法计算得到的边坡破坏面与 FLAC3D计算得到的初始失稳区域的主滑动面是一致的，该滑坡是以推移为主牵引为辅的复杂滑移机制滑坡。
Abstract
Base on the investigation and detection for the tailor rock landslide in Chuan-ian railway K119,the basic characteristics and forma-tion mechanism of the landslide are described. The stability of the slope is evaluated by Bishop method and the safety factor is analyzed. The failure process of the slope is simulated and analyzed by using FLAC3D software. The results show that the sliding surface obtained by two differ-ent methods is the same. Furthermore,the mechanism of the landslide is complex and the pushing effect is main with the tractive action.
