芜湖弯石公路清弋江桥动荷载试验研究
|
摘要
芜湖弯石公路清弋江桥加固后,运用动荷载试验原理,对该桥进行荷载试验,试验结果表明桥梁的行车动挠度、冲击系数、阻尼比等均属正常范围,验证了桥梁的质量和工作性能与加固设计要求相符,说明桥梁竖向刚度满足加固设计要求。
After Qinghua River Bridge of Wanyi Highway in Wuhu is reinforced, the load test is carried out for this bridge by the dynamic load test principle. The test result makes clearly that the driving dynamic deflection, shock coefficient, damping ration and etc. of the bridge all belong to the normal range, verifies that the bridge quality and the working performance conform to the requirements of the reinforcing design, and explains that the vertical rigidity of the bridge meets the requirements of the reinforcing design.
