摘要
从结构力学的理论出发 ,考虑影响车辆冲击力的各种因素 ,提出了路况系数和冲击动力放大系数两个新概念 ;克服了目前简单确定冲击系数和直线中插确定冲击力的弊端。从而使桥梁所承受的车辆冲击力的计算更接近于真实状况。
In compliance with the theories of structural mechanics,and in consideration of all factors that may influence vehicle impact,two new concepts,i.e. road condition factor and amplification factor of impact dynamics are proposed. The concepts reject the defects of determining the factors in a simple way and by way of linear interpolation,thus make the calculation of the impacting force withstood by bridges closer to the real state.
