某五跨预应力连续梁桥静载分析

Static Analysis on a 5 Span Prestressed Continuous Plate Girder Bridge

以青岛市某5跨预应力混凝土连续梁桥的静载试验为背景,通过对结构的应变、挠度等参数进行测试,进而对结构的刚度、强度和抗裂性能进行分析,达到了评定该桥实际承载能力。并为同类桥型设计和施工积累了资料数据。

Load test is a major way to predict the working condition and the carrying capacity of a bridge. Based on the static load test of a continuous prestressed girder bridge, the stiffness, strength and the anticracking ability of the structure was analysed to evaluate the load carrying capacity of the bridge and recalculate the ability of the bridge in the circumstance of new specifications.
