Research on Static and Dynamic Load Test of Xinmin Minjiang River Bridge

Using the equivalent load loading test to simulate the working conditions of longspan continuous rigid frame bridge in the condition of greatest loads.The actual load-carrying capacity and perfoemance capabilities in the design using load can be eatimated according to test and analyze girder deflection and the control sectional stress between main girder and main pier under static load.The natural vibration characteristics of the bridge superstructure and the dynamic performance in the long-term service load can be realized according to dynamic loading test.And the impact action of bridge span structure under traveling crane can be analyzied.The bridge operation congdition can be forecasted and it can provide technical basis for the bridge maintenance and management.
