洪家渡水电站厂房上部钢结构负荷试验及其结果分析

Analysis on Load Test of Steel Structure on The Top of Powerhouse of Hongjiadu Hydropower Station & Its Results

阐述了贵州乌江洪家渡水电站厂房上部新型钢结构排架柱、吊车梁负荷试验时的变形、振动的观测方法与结果,并对结果进行了分析处理。试验结果表明:洪家渡水电站厂房排架柱、吊车梁负荷试验时的变形位移值及振动频谱分析最大振幅值都在设计容许范围之内,从而证明该新型结构在水电站的推广价值。

This article introduces the methods and results of observing vibration and deformation of crane beams and framed columns-steel structures on the top of powerhouse when them were in load test, as well as analyzes the results. The results of the test made known that the values of deformation and vibration of the crane beams and framed columns of Hongjiadu Hydropower Station powerhouse when they in load test are in the scope of design permission. This proves that the new structure has value of popularity in hydropower station construction.
