摘　　要：水工钢闸门安全检测是判断水库钢闸门运行安全度的重要手段,对于运行几十年的钢闸门更应进行安全检测。以小南川水库为例,对其进行外观、门体材料及尺寸、腐蚀、焊缝、应力与启闭机性能检测。运用有限元软件ANSYS对弧形工作钢闸门的受力状态进行模拟计算,并对校核洪水位下弧形工作钢闸门进行应力分析。根据结构应变实测结果与模拟计算结果,对弧形工作钢闸门的安全状况进行分析,提出检测结论和维修方案建议,为类似工程提供参考。The safety detection of hydraulic steel gate is an important way to judge the safety degree of the operation of the steel gate,which is particularly important for the old equipment that has been running for several decades. Its appearance inspection,door material and size detection,corrosion detection, weld inspection, stress detection and performance testing of the hoist are carried out by taking the Xiaonanchuan Reservoir as an example. The finite element software ANSYS is used to simulate the stress state of the working steel radial gate,and the stress analysis of the working steel radial gate under the check flood level is carried out. According to the test results and simulation results,the security situation of steel arch-gate is analyzed,test conclusions and maintenance plan advice is proposed. It also serves as a reference for similar projects.
