摘　　要：阐述了水工平面闸门结构的地震响应分析方法,并采用典型地震波加速度-时间历时曲线进行泄洪闸正常挡水状态的地震响应分析。结果显示,在地震设防烈度8度条件下,闸门结构的地震动应力和位移均远大于规范规定值,结构受到地震损坏的可能性很大。在此基础上,对闸门结构进行抗震设计修改,改善了结构的抗震能力。The paper first elaborates the analytical method of seismic response of hydraulic plate gate,and then analyses the seismic response of release gate under the general water-retaining condition by the method of the seismic wave acceleration-time process curve.The result indicates that when the fortification intensity of earthquake is eight degree,dynamic stress and displacement of gate are much more than specified value of discipline,which states that the probability of seismic damage of gate is very high.On the basis, the paper modifies the gate according to the requirement of seismic design,approving the seismic capability.The research guides the seismic safety design of hydraulic plate gate.
