摘要
通途路原设计荷载为汽-超20、挂车-100,要拓宽、改建成设计荷载为城-A级。由于车辆荷载及桥面铺装等静荷载的增加,需对旧桥进行检测及加固,以保证改扩建后其性能满足设计要求。
When being widened and rebuilded,the designing load of Tongtu road was changed from former load(Truck-Load over 20 and trailer 100)to be class city-A. Because of the increase of vehicle load and bridge pavement static load,the old bridge is needed to be detected and reinforced so as to make the performance after rebuilding satisfy the designing requirement.
