| 摘 要： | 对坝基含双斜面软弱结构面的某重力坝工程挡水坝段,以非线性有限元法进行静力荷载作用下的深层抗滑稳定研究.计算结果表明,当坝基内含有双斜面软弱结构面时,在超载过程中,坝体沿该双斜结构面向下游滑动,其中坝踵附近的软弱结构面最危险,坝趾下游结构面次之,判定超载安全系数K=3.0～4.0.并通过刚体极限平衡法对有限元计算结果进行...

| Abstract: | The nonlinear finite element method(FEM) is applied to study the stability against sliding at deep level of foundation in a gravity dam with double inclined wedge.The results show that when the dam foundation contains double inclined weak wedge,the dam will slide to the downstream along double inclined wedge of foundation during overloading,and the weak structural planes near the dam heel is destroyed firstly,that near the dam toe followed in the requirement of overload safety factor;K = 3.0 -4.0.Furthermor... |
