变高度箱形梁桥动载试验研究

Research of high-changed box beam motive loading test

结合具体工程实例,对大跨径变高度箱形梁桥进行了动载试验,结果表明理论计算值与试验结果吻合较好,得出了该桥的动力性能良好的结论,为该桥的正常运营提供了可靠的试验依据。

Combined with concrete project, it makes a motive loading test on large-span high-changed box beam. The result shows, theoretical calculation is just the same with the testing results, and concludes that the motive function of this bridge is good, meantime, offers stable testing foundations for the normal operation of this bridge.
