小湾大桥荷载试验

Loading Test on Xiaowan Bridge

通过对小湾大桥的荷载试验,测试其最不利荷载下桥梁的应力(应变)、挠度,以此推断桥跨结构的强度和刚度;针对桥梁荷载试验的重要性,总结了桥梁进行荷载试验的条件,详细介绍了桥梁静载试验的目的、内容和过程,指出在进行桥梁荷载试验时,应将理论和实际充分结合起来,从而对桥梁做出准确的评估。

The strength and rigidity of the bridge superstructure are deduced from the measurement of the stress and deflection of the bridge under the most disadvantageous load through loading test on Xiaowan Bridge. According to the importance of bridge loading test ,the conditions for bridge loading test are summarized, the objective, contents and process of static test of a bridge are in detail introduced,the theory should be sufficiently combined with practice when the loading test of the bridge is conducted so that accurate evaluation on the bridge can be made.
