16 m预应力空心板梁桥动静载试验实例探讨

The static and dynamic loading test of 16 m prestressed concrete hollow slab beam bridge

桥梁在运营期间,结构会受到各种因素长期的影响,为判定桥梁结构的受力性能以确定桥梁的实际运营状态有必要对桥梁进行静力荷载试验和动力荷载试验。简支铰接空心板梁桥是梁式桥中应用最为广泛的一种桥型,对湛江海丰桥进行了动静载试验分析,简述动静载试验方案的布置,综合分析实测试验结果,将实测值与理论值进行比较,再结合规范对桥梁结构的状态进行评估,为动静载试验研究作一些参考。

Bridge structure plays a crucial role in the society and it is affected by many factors for a long time during the operation. In order to ensurethe safety of bridge structure, static and dynamic load test are necessary carried out on the bridge. Simply-supported hinged joint celluar slabbridge is widely used in beam bridge. A brief description of testing program and analysis of test results stated through testing the Haifeng bridge inZhanjiang city. Finally, bridge structure evaluated with relative codes and some existing research, which can provide a reference for the future analysisof similar bridges.
