摘要
本文采用块体极限平衡Ｓａｒｍａ法和非线有限单元分析法对小山水电站厂房边坡岩体稳定性进行了分析研究。综合两种方法的计算成果分析，厂房边坡岩体在自然状态下是基本稳定的，整体安全系数均大于１．３０，但在边坡岩体内存在部分张应力区和塑性区。若考虑Ⅵ度地震，厂房边坡岩体Ｓａｒｍａ法和有限元计算的安全系数分别为１．１８和１．１６，处于极限平衡状态。考虑到长期稳定边坡安全系数大于１．３０的规范要求，需进行一定的加固处理，保障厂房安全运行。
In this paper, the Sarma non vertical slice method and non linear finite element method are used to analyze the slope stability in Xiaoshan Power Staton at the workshop which is 176 m high and slope angle is 35°as a whole. On the basis of analysis results by using the methods, the safety factor of slope is more than 1.30 which means the slope of workshop is stable in the natural state though there exits some tensile zone and plastic zone in rockmass on the slope. In consideration of the earthquake with magntude of 6.0 it is still in a limit equlibrum. But it is necessary to reinforce part of the slope in order to guarantee the workshop of Xiaoshan Power Station.
