摘要
在拱坝研究中,由于岩体中存在断层、节理等不连续面,拱坝坝体及坝肩三维稳定分析十分复杂。以牛头山 拱坝为工程实例,分别进行了三维有限元计算和结构模型试验。研究表明计算结果和试验结果比较接近,计算和试 验得到的破坏机理也很相似。
The 3-D stability analysis of arch dams and their abutments are very complicated due to discontinuities such as faults and joints in the rockmass. In this paper, both 3-D finite element computations and structural model tests were applied to the stability of Niutoushan arch dam. It is concluded that the results of computation agree with those of experiments, and the failure mechanism provided by computation and model test are very similar.
