摘要
针对江坪河电站溢洪洞开挖后的稳定性进行了三维非线性有限元计算分析,通过拉应力区分布、拉应力区深度等方面综合评价了洞室在开挖未支护和开挖支护工况下的稳定性,为设计和施工支护优化提供了重要参考。
In this paper, we calculate and analyze the stability of underground cavern after excavation with 3-D non-linear finite element method. Based on analyzing distribution of tensile stress regions, depth of tensile stress regions, the massive stability of the side slope isucomprehensively estimated under un-supported working conditions of excavation and supported working conditions of excavation,which provides the important reference value for support optimization of the design and construction.
