摘要
通过对比各国公路桥梁规范关于汽车冲击系数的计算公式,分析了各种冲击系数计算方法的差异,并就几座实际桥梁进行了对比研究,可以为公路桥梁结构设计提供参考,同时提出了公路桥梁汽车冲击系数研究的重点。
By comparing the formulas of impact coefficient caused by vehicle among the standards of bridges, the difference is analysed among impact coefficients; the farther study is carded out by comparing several bridges in actual existence. This paper can give some advice for the design of highway bridges, and point out the emphasis for the study of impact coefficient caused by vehicle for highwaybridges.
