摘　　要：以某混凝土重力坝为工程背景,采用ANSYS14.0有限元分析软件对该坝27#段面进行了数值模拟,分别进行了静力分析与动力分析。分析得出了在实际水位作用下的坝顶水平位移值及设计地震烈度情况下的地震对大坝变形位移的影响值,并与激光准直测量的监测数据进行对比分析,得出大坝目前及未来仍然处于安全稳定状态,为大坝的安全稳定运行提供参考。Based on the engineering background of a concrete gravity dam, this paper adopts ANSYS14.0 finite element analy sis software for the 27 # dam section to have a static and dy- namic numerical simulation analysis. Research data about the ac- tual horizontal dam top displacement under the action of water level and earthquake intensity influence on dam displacement and deformation are compared with the monitoring data of laser colli- mation measurement. Comparison and analysis results show that the dam at present and in the future is still in a safe and stable state. Therefore, this research can provide reference to the secu rity and stability operation of the dam.
