| Abstract: | Taking an RCC arch dam for example,the dam structure,foundation conditions,loads and operation conditions(including unexpected loads and operation conditions),etc,are simulated by using the finite element method.Through computational analysis of the dam stress field,displacement field,seepage field,stability against sliding and strength reliability,the paper studies the reasons and mode of damage,and determines the weak parts of a typical dam. |
