摘　　要：随着国家交通运输设施建设的高速发展,桥梁作为整个交通运输网络的纽带,被大量应用到工程中。桥梁结构的安全直接影响着交通运输事业的发展,为了确保桥梁工程的运营安全,需要定期对桥梁进行健康检测。如何快速准确地检测出桥梁病害,就成了一个重要课题。通过对某简支空心板桥的检测方案进行优化设计,研究了桥梁上部结构、下部结构静载试验的内容和注意事项。对试验过程中主梁盖梁的测点布置方案进行了探讨,分析了不同加载工况对检测结果的影响。在综合分析现场试验条件和理论计算的基础上优化了该桥的检测方案,为今后同类型桥梁的检测方案设计提供了参考。As the link of the whole transportation network,with the rapid development of national transportation facilities construction,bridges are widely used in engineering.The operation safety of bridge structure has a direct impact on the development of transportation.In order to ensure the operation safety of bridge engineering,it is necessary to carry out regular health inspection on bridges.So how to quickly and accurately detect the bridge disease has become an important topic.Through the optimization design of the detection scheme of a simply supported hollow slab bridge,it studied the contents and precautions of the static load test of the superstructure and substructure of the bridge,probed into the arrangement scheme of the measurement points of the main beam and the bent cap in the test process,and analyzed the influence of different loading conditions on the detection results.Based on the comprehensive analysis of the field test conditions and theoretical calculation,the best detection scheme of the bridge was obtained,which provides a reference for the detection scheme design of the same type of bridge in the future.
