夔门大桥成桥荷载试验研究

Study on Load Test of Fenjie Yangtze River Bridge at Completion Stage

介绍夔门大桥大跨径斜拉桥荷载试验的主要内容和方法,并结合理论计算,对该桥梁结构的实测应力、挠度进行对比分析。试验结果表明,该桥理论分析和设计计算方法可靠,施工质量优良,桥梁刚度和承载能力满足设计要求。研究结果可为同类型桥梁的设计和成桥试验提供参考。

This article introduced the contents and methods of load test for Kuimen Bridge, and through reasonable theoretic calculation, compared and analyzed the measured stress and deflection. The results indicated that the theoretic computation method is liable; the construction quality of the bridge is excellent, the rigidity and the carrying capacity are satisfactory with the requirement of design. The results of the bridge may provide reference to other similar bridges.
