摘要
利用安装在广东佛开高速公路上的动态称重(WIM)系统,分别在两个不同位置的四个断面采集了为期将近一年的测试数据,对不同车道车流的分布及荷载组成进行了统计,总结了佛开高速公路车流的交通量、车重、轴重分布以及车头时距和车头间距分布规律。并对桥梁结构在实测荷载作用下的效应进行了分析研究。
Using the weigh-in-motion(WIM) system which is installed on the Fokai Highway in Guangdong, the test data of four sections at two different locations for nearly one year are collected.The distribution and load composition of traffic flow in different lanes are statistically analyzed.The traffic volume, vehicle weight, axle load distribution and the distribution of the time and space headway of the Fokai Highway are summarized.Meanwhile, the effect of the bridge structure under the measured load is analyzed.
