选择中国、美国、英国、加拿大等国的公路桥梁标准车辆荷载,比较在虚拟大跨径简支梁桥结构上的荷载效应,认为我国现行的标准车辆荷载尽管有需要改进的地方,但其在特大跨径桥梁的设计中还是基本适用的。
Select the standard vehicle loads of highway bridges in China, the United States, Britain, Canada and other countries. Comparing the load effects on the structure of the virtual long-span simple-supported beam bridges, we think that although the current standard vehicle loads in our country are in need of improvement, Large span of the bridge design is still basically applicable.
