| 摘 要： | 在细致模拟溪洛渡高拱坝坝址区层间层内错动带空间展布和连通特征的基础上,采用三维非线性有限单元法,定量分析了坝肩岩体变形和超载破坏规律,并用点安全度、超载及综合安全系数评价坝肩岩体稳定性。结果表明:坝肩整体刚度好,承载能力强;坝肩岩体正常蓄水超载安全系数为6.0,综合安全系数为4.8,满足整体抗滑稳定安全要求。

| Abstract: | Based on delicate and careful simulation of between-layers and inside layer shear zones in Xiluodu dam site area,deformation and over-load failure mechanism of the dam abutment rock mass are studied quantitatively using 3 dimensional non-linear finite element method,and stability of the dam abutment rock mass is evaluated by way of spot reliability,over-load and comprehensive safety coefficient in this paper.The study results indicate that overall rigidity of the dam abutment is high and its bearing capacity is powerful,at normal pool level over-load safety coefficient of the dam abutment rock mass is 6.0 and comprehensive safety coefficient reaches 4.8.All of them satify the criterion for integral antiskid stability. |
