摘　　要：巴基斯坦Dasu水电站将1条导流洞改造成2条冲砂洞,为了验证冲砂洞工作闸门的安全性,基于有限元软件ANSYS,建立工作闸门的有限元模型,综合考虑静水压力、波浪压力、淤沙压力、重力等主要荷载,对闸门在最大设计水头进行闭门工况下的静力分析和地震时程分析,得出闸门的应力和变形情况,对闸门的强度和刚度进行校核,评估闸门的安全性。结果表明:冲砂洞工作闸门满足强度和刚度要求,该研究为同类闸门安全性的评估提供参考。The Dasu hydropower station in Pakistan transformed one diversion tunnel into two sand flushing tunnels. In order to verify the safety of the service gate of the sand flushing tunnel, a finite element model of the service gate was established based on the finite element software ANSYS. Considering the main loads such as hydrostatic pressure, wave pressure, silt pressure, gravity and so on, the static analysis and earthquake time-process analysis of the gate under closed working conditions of maximum design head were carried out, and the stress and deformation of the gate were obtained. The strength and stiffness of the gate were checked to evaluate the safety of the gate. The results showed that the service gate of sand flushing tunnel met the requirements of strength and stiffness, and this study could provide a reference for the safety evaluation of similar gates.
