摘要
根据规范对1-140m悬链线无铰拱桥分别按照公路—II及特种平板挂车—300进行受力分析,确定设计活荷载。为满足大件运输的大跨径桥梁设计提供参考。
In order to determine the maximum load, the catenary fixed arch bridge with 140 meters span was respectively computed under the action of vehicle load and heavy-cargo transportation based bridge design specifications. The result according with the engineering practice shows that it has the good practical application value and prospect, and its methods and conclusions can be a reference for other similar projects.
