摘要
结合拱坝坝肩与坝基的地形、地质特征以及软弱结构面分布状况,通过ANSYS软件建立拱坝天然地基条件下的三维数值模型,并进行超载法计算,分析坝体变形与应变特征、坝肩和断层的变位分布特征、坝肩的破坏形态和过程,得到整体稳定超载安全系数,评价拱坝的安全度,为工程设计、施工和加固处理提供依据.
According to the topographical, geological features, the distribution of weak structure of the arch dam, a three-dimensional numerical model of arch darn under the natural foundation conditions is established by ANSYS software. Using overloaded method, which can analyze and calculate the displacement of the dam and abutment, the relative displacement of weak structure plane, and the failure pattern and process of the dam and abutment just as in the model test, the overload coefficient of overall stability is obtained. It can evaluate the safety of arch dam. The results have provided the important scientific basis for the design, construction and reinforce- ment of the project.
