摘　　要：北川县擂鼓镇凤凰山滑坡为由"5.12"汶川大地震诱发的一特大型滑坡。本文在对该滑坡进行野外地质调查工作的基础上,总结了该滑坡的地质特征,分析了形成机理;采用极限平衡法对滑坡稳定性进行了分析和评价。研究表明在自重情况下,滑坡3-3'剖面为不稳定剖面,并在滑坡后缘部分和中间一小部分将会出现滑动,通过分析判定,该滑坡的状态为欠稳定性状态。A large landslide in Beichuan County of Leigu town landslide in Lantau Peak ＂5.12＂ earthquake induced by. This paper based on the field geological survey in the land- slide, summarizes the geological characteristics of the landslide, formation mechanism is analyzed; by using the limit equilibrium method for analysis and evaluation of landslide stability. Studies show that in the case of landslide weight, 3 - Y section for un- stable section, and the emergence of sliding in the landslide sec- tion and the middle of a small part of will, through the analysis to determine the landslide stability state of state owed.
