摘要:

为准确测量水电站潜没式弧形闸门的结构强度,在水电站调节水位时,采用应变电测法对某水电站潜没式弧形闸门进行3个工况下的结构应力测试,考虑到潜没式弧形闸门的特殊工况,对电阻应变计进行了有效防护,以保证测试系统的稳定。测试结果显示,测试系统稳定,各测点数据正常。结合弧形闸门运行状态对测试数据进行分析,掌握弧形闸门的应力分布情况,评价弧形闸门的结构强度安全。

Abstract:

In order to measure the structural strength of the submerged radial gate of hydropower station,strain electrical measurement method is used to test the structural stress of a submerged radial gate under three working conditions when hydropower station adjusts its water level.Considering the special working condition of submerged radial gate,effectively protection is made on resistance strain gauge to ensure the stability of the test.The test results show that the test is stable and the data of each test point is normal.The test data is analyzed in combination with the running state of the radial gate,the stress distribution is obtained.And the safty of structural strength of the radial gate is evaluated.
