因此要研究公路桥梁设计汽车荷载的适应性，为修编汽车荷载标准服务。

Therefore, the research on adaptability of present highway bridge vehicle design load is needed to service the revision of the standard.

但由于我国现行公路桥梁的抗震设计规范存在不足，致使设计细部构造时没有统一的标准。

But because of the lack of the current seismic ability design criterion of Highway bridge, there isn't a uniform standard in the bridge detailed component's seismic ability design.

可以为公路桥梁设计汽车荷载的修编和现行公路桥梁设计汽车荷载限载标准的制定提供依据。

But also provides evidence to modify highway bridge design vehicle load and formulating the existing highway bridge design vehicle load limit.
