摘要
为了检测信阳河大桥当前的承载能力,对该桥进行了静动载试验.介绍了对该桥的检测内容、加载工况、测试方法以及静载试验结果.由检测试验结果可以得出结论:该桥的整体强度和刚度基本上能满足正常使用要求,承载能力基本上达到了其设计要求.
In order to test and evaluate the loading character of Shihe bridge in Xinyang city, the static and dynamic test is performed . The testing content, loading mode, testing method and the testing results of dead load are introduced. The result indicates that the global strength and rigidity of the bridge can meet the demand of normal use, and the loading capacity satisfies the design requirement.
