摘要
通过对乌石北江特大桥实施静动载试验,测量并分析荷载作用下控制截面的主梁挠度、主梁应变和主塔偏位等,比较该桥各指标的实际值和理论设计值,结果表明该主桥在力学性能上满足设计要求。
Through the implementation of dynamic and static load test for Wushi Beijiang Bridge, the deflection and strain of main girder, as well as the displacement of main tower of the critical section under load have been surveyed and analyzed, comparison of each indexes between theoretical value and actual value has been conducted, the results have shown that the mechanical properties of the bridge can meet the design requirements.
