摘　　要：为研究超期运行多年的弧形闸门对水库大坝安全评级的影响,以水府庙水库大坝弧形闸门金属结构的安全评价为例,在现场检查与安全检测的基础上,分析了其抗洪能力、渗流安全、结构安全,并就金属结构安全进行了复核计算,从而对弧形闸门进行了综合安全性态分析与评价。结果表明:虽然水府庙水库弧形闸门金属结构已超过报废折旧年限,但弧形闸门及其启闭机运行状况、现状基本正常,水府庙水库大坝泄洪闸金属结构基本安全。研究成果可为水工金属结构尤其是超期在役弧形闸门等金属结构的安全评价分析提供参考。In order to research the impact of arc gate that has been operating for many years on the safety rating of the reservoir dam,taking the safety evaluation of the metal structure of the arc gate of Shuifumiao Reservoir as an example and on the basis of on-site inspection and safety testing,this paper analyzes its flood resistance,seepage safety,and structural safety,and conducts a review of the safety of the metal structure to analyze and evaluate the comprehensive safety.The results show that although the metal structure of the arc gate has exceeded service life,the arc gate and hoist machine are still in normal operation and the metal structure of flood release arc gate is safe basically.The study result can provide a useful reference for the safety evaluation and analysis of hydraulic metal structures,especially the overdue in-service arc gate and other metal structures.
