中文摘要:

      广东省东莞市某跨线立交桥于2004年建成通车，为检验该桥的承载能力和正常使用状态是否满足设计要求，对该桥进行了荷载试验。介绍了荷载试验的检测内容、检测方法、加载工况以及检测结果。由检测结果可以得出，该桥的承载能力和正常使用状态满足设计荷载等级的要求，可以正常使用。

英文摘要:

      In 2004, an overpass was completed and opened to traffic in Dongguan City, Guangdong Province. In order to test whether the load bearing capacity and normal working condition meet the design requirements of this bridge, load test has been carried out. The contents, methods, loading states and results of this load test are introduced in this paper. It can be concluded from the results of load test that the load bearing capacity and normal working condition meet the design requirements of the bridge, and the bridge can be kept in use regularly.
