摘　　要：水工弧形钢闸门振动问题对水利枢纽营运安全具有重要意义。分析结构形式、工作性态与水力环境特点,得到环境边界条件、水流特性与结构自身形式对振动特性影响规律。数值计算与监测资料分析表明,开启角度、相对水深和结构形式均影响闸门振动位移、振动加速度、基频、自振频率等变化规律。The vibration of hydraulic radial steel gate is of great significance to the operation safety of water conservancy project.By analyzing the structure form,working behavior and hydraulic environment characteristics,the influence laws of environmental boundary conditions,flow characteristics and structure form on vibration characteristics are obtained.The numerical calculation and monitoring data analysis show that the opening angle,relative water depth and structural form all affect the variation of vibration displacement,vibration acceleration,fundamental frequency and natural frequency of the gate.
