摘　　要：某大型水电站导流洞进口闸室结构为一个典型的三维受力结构,特别是封堵期作用于闸门上的最大水头达到120m,水推力大。为了保证导流洞进水口闸室结构在复杂受力情况下的安全可靠性,建立闸室整体有限元模型,并参考类似工程相关计算,主要对该导流洞进口闸室结构在完建期、运行期和封堵期3种工况进行三维计算分析。The inlet lock chamber structure of a large hydropower station diversion tunnel is a typical three-dimensional stress structure.The maximum water head acting on the gate during the sealing period reaches 120m,with a high hydraulic thrust.In order to ensure the safety and reliability of the intake lock chamber structure of the diversion tunnel under complex stress conditions,this paper establishes an overall finite element model of lock chamber.And referring to similar engineering calculations,it conducts three-dimensional calculation analysis on the inlet lock chamber structure of the diversion tunnel under three working conditions:completion period,operation period,and sealing period.
