高寒高海拔地区库岸边坡稳定性分析

Analysis on bank slope stability of reservoir in alpine-cold and high altitude area

文中以浪加河上某座水库区的一个库岸边坡为例,根据工程勘察资料和室内实验分析,运用块体理论以及有限元方法,对库岸边坡进行局部和整体稳定性进行分析,同时运用强度折减法加以考虑岩土体冻融参数的变异性,可以得到更加合理有效的结果。

Taking the bank slope in some a reservoir area in Langjiahe River as an example, the local and integral stability of reservoir bank slope are analyzed by using block theory and finite element method based on the analysis of engineering survey data and laboratory experiment, at the same times, the strength reduction method is used to consider the variation of freezing thawing parameter of rock and soil mass, which could obtain the rational and effective result.
