德阳王官村互通式立交桥连续梁静动荷载试验分析

Loading inspection test analysis of interoperability overpass continuous beam in Wangguan Village of Deyang

为了解德阳市王官村互通式立交桥在荷载作用下的实际工作状态,对该桥梁进行了静动荷载试验。试验首先基于通用有限元程序软件进行理论计算,并根据理论计算结果作为控制因素进行现场检测试验,并对检测过程及该桥使用状况进行总结分析。试验结果表明,该桥使用性能较好,处于弹性工作状态,承载能力满足有关规范的要求。

To understand the real work condition of interoperability overpass continuous beam in Wangguan Village of Deyang on the loading,the static/dynamic load tests have been carried out.We firstly computed the theory consequence based on the procedure software in general,and then actually tested the bridge by comparing with the theory effect.There are some reasonable analysis about the loading procedure and the back use.The result shows that usage function of approach structure is better,the loading ability satisfy with the request of our country normative.
