摘要
荷载试验可了解桥梁结构在荷载作用下的实际工作状态。本文主要从测试截面、测试方法的选取、加载方式的布置以及加荷过程等几个方面论述了静载荷试验在青岛创意大桥变形监测中的应用。最终的监测数据表明,静载荷作用下该桥梁结构控制截面的挠度、应力、残余变形和索塔偏位均小于理论临界值,桥梁结构满足使用要求。
The load test can help understand the actual working condition of bridge structure under load action.In this paper,the application of static load test in deformation monitoring of Qingdao Chuangyi bridge was described in terms of several aspects such as the test section,test method selection,loading arrangement and loading process.The final monitoring data indicate that under static loading,the deflection,stress,the residual deformation and the cable support tower deviation of the bridge structure control section are all less than the theoretical deviation threshold,and the bridge structure meets the application requirements.
