摘要:
为获得高速公路车流荷载的时空分布特征及演变规律，基于大量WIM数据，对多条高速的车流参数进行时空演变分析，并进一步分析不同车道的荷载极值及其效应。研究结果表明：2车道高速公路各车道车流状态同质性较高，3车道高速各车道车流状态差异较大；各车型对车道的选择概率较稳定，中间车道的车型分布较复杂，导致其平均车速相对较低；平均车重随时间呈24 h周期性变化，各车道平均车重的幅值差异和波动较大且中间车道承担的荷载变异水平相对较高；平均车速与车重的周期变化类似；车重荷载极值及效应由车道内向车道外呈递增趋势，其中慢车道的外推荷载极值及效应相对较大，需在路桥结构设计及运营养护中引起重视。
Abstract:
In order to obtain the time-space distribution characteristics and evolutionlaw of traffic load on expressway,thetime-space evolution characteristics of traffic flow parameters of multiple expressways were analyzed based on a large number of weight in motion (WIM) data,and the load extreme value and its effect of different lanes were further analyzed.The results showed that the traffic flow status of each lane of the two lanes expressway was more homogeneous,while the traffic flow status of each lane of the three lanes expressway was more different.The selection probability of each vehicle type to the lane was relatively stable,presenting obvious layered characteristics.The distribution of vehicle types in the middle lane was the most complex,resulting in a relatively lower average speed.The average vehicle weight changes periodically with time,and the cycle was about 24 hours.The amplitude difference and fluctuation of average vehicle weight in each lane werelarge,and the variation level of load borne by the middle lane was relatively higher.The average speed had a cycle change law similar to the vehicle weight.The extreme value and effect of vehicle weight load increased from the inside lane to the outside lane.The extreme value of extrapolated load and its effect of slow lane was relatively larger,so the attention should be paid in the design of road and bridge structures and their daily maintenance.
