西宁市林家崖危岩和滑坡特征及其稳定性评价

Features of the Linjiaya dangerous rockmass and landslide locatedin Xining city and their stability evaluation

在对西宁市林家崖危岩体及滑坡的详细勘测基础上,就其特征和成因机制进行了阐述;采用萨尔玛法、简布法、剩余推力法三种极限平衡法对各个断面进行了稳定性计算,评价其稳定性;其计算结果与监测资料和宏观变形相吻合。

Based on the detailed investigation of the Linjiaya dangerous rockmass and landslide, this paper expatiates on the characters and the formation mechanics of these geologic bodies. And by use of the methcds of Sarma, Janbu, and Residual thrust, the paper calculates respectively the main transects＇ stability coefficients, evaluating the stabilities of them. The results conform well to the monitor datum and the macroscopical deformations.
