大跨径桥梁车辆设计荷载思考

Thinking on design load of long span bridge vehicle

以工程项目资料为研究背景,解析大跨径桥梁设计过程中车辆设计荷载确定方式,在分析国内车辆荷载设计标准基础上,调查大跨径桥梁交通情况,从而采取有效的设计方式对车辆荷载设计内容进行解析,实践可知,以当地所运行的车辆通行量以及车辆载荷为主要的依据,可以确定大跨径桥梁车辆荷载数值。

Taking the engineering project data as the research background,the method of determining the vehicle design load in the large span bridge design process is analyzed. On the basis of the analysis of the domestic vehicle load design standard,the traffic situation of the long-span bridge is investigated,and the effective design method is adopted to analyze the content of the vehicle load setting. The vehicle load and vehicle load are the main basis for determining the vehicle load values of long-span bridges.
