摘　　要：由于江垭水库中孔高压弧形闸门支铰止轴板固定螺栓剪断,对闸门支铰进行改造,对闸门支铰改造设计、施工和闸门支铰改造后空载、负载启闭试验进行了阐述,并分析总结了深水高压弧形闸门支铰改造和运行维护管理经验。The trunnions of radial gates in the mid-discharge orifices of Jiangya Reservoir are modified because of the breakage of set bolts of radial gates. The design and construction of modification and the no-load and load operation tests after the completion of modification are introduced. The experiences of modification and operating management of high-pressure radial gates are also summarized herein.
