摘要
结合东庄拱坝设计,利用三维设计模型分离拱坝一定高程范围内的潜在滑动的危险块体,建立恰当的三维坐标系,采用刚体极限平衡法计算拱坝坝肩抗滑稳定,证明该方法计算效率高,结果准确,简单易行。
The stability against sliding in abutments of Dongzhuang Arch Dam is analyzed with three-dimensional rigid - body limit equilibrium method. The potential sliding rock blocks within a certain scope of the dam abutments are identi- fied with the three-dimensional design model. Appropriate three-dimensional coordinates are then constructed to carry out the analysis. It shows that the proposed method is of good accuracy and efficiency.
