摘　　要：拉西瓦水电站泄洪底孔4 m×9 m-132 m事故闸门属于目前中国高水头门型。门槽水力学比较复杂,采取何种措施以防止闸门振动、保证闸门和门槽运行安全,具有广泛的代表性。通过对该闸门门型的选择、闸门和门槽的结构特点、数值分析、水力学和振动试验、三维有限元计算等方面的介绍,可为此类型闸门设计提供参考。The （4 m × 9 m - 152 m） emergency gate of the bottom outlet of Laxiwa hydropower project is the high - head type gate in China now. With complicated slot hydraulics, how to take effective measures to prevent gate vibration and ensure the operation safety of gate and slot is of wide representativeness. This paper presents the selection of gate type, the structure features of gate and slot, numer- ical analysis, test on hydraulics and vibration, and 3D finite element calculation, which provides reference for the design of this type of gate.
