摘要:
正在建设中的西南某水电站，在开挖过程中，右坝肩岩体的不同部位出现了不同程度的变形破坏迹象，局部出现了小规模的跨塌现象.为了评价开挖对边坡的影响，根据施工开挖的顺序，应用三维弹塑性有限元数值法对坝肩边坡开挖后的变形、应力状况及破坏区分布进行模拟，揭示边坡可能的失稳的部位，并对边坡的支护方案提出建议.
Abstract:
Some evidences of failure by rupture appeared on the right dam abutment slope of a southwestern hydropower station during the excavation,and collapses took place in some local zones.In order to evaluate the effect of excavation,according to the order of the excavation,the method of 3-D elastoplastic finite element analysis is used to simulate the deformation,the distribution of stress and failure area,so the possible failure location of the slope can be revealed,moreover table a proposal about the support blue-print.
