摘　　要：对于设计车速为80 km/h的双管6车道高速公路盾构隧道,受盾构机及资金限制,内侧车道设计宽度为3.5 m,相比一般高速公路路段规定减小了0.25 m。以上海市沿江特大高速公路隧道为研究对象,分析车道宽度的这种变化对车辆运行的影响。依照隧道设计方案,分别建立内侧车道宽度为3.75 m和3.5 m的2种模拟场景,基于同济大学高仿真驾驶模拟器展开对比试验。通过试验采集同一驾驶员在2种场景下的车速、轨迹偏移等参数,绘制隧道路段平均车速、平均轨迹偏移分布图,比较2种场景下运行参数平均值差异,发现2种场景下的车速、轨迹偏移变化趋势基本一致。利用配对t检验方法验证参数差异的显著性,结果显示,内侧车道宽度由3.75 m减小为3.5 m,对于车辆速度、轨迹偏移没有显著影响。For 6 lane highway tunnel whose design speed is 80 km/h, limited by the shield machine and economic factors, the width of inside lane is decreased from 3.75 m to 3.5 m. The effect on driving behavior caused by the decrease is unknown. A super long freeway tunnel in Shanghai named Yuejiang tunnel was studied in this paper. Based on Tongji University＇s driving simulator, two tunnel models were established according to the design scheme. The inside lane widths of the two tunnels are 3.75 m and 3.5 m respectively. Data on operating speed, trajectory offset of the same driver in two different scenarios were collected. By drawing diagrams for the tunnel road average speed, average trajectory deviation distribution, an average driving parameters comparison was made between the two scenarios. Paired t test method was used to examine whether the parameters differ significantly between the two scenarios. Analysis shows that the vehicle speed and trajectory are not significantly affected by the decrease in the width of the inside lane from 3.75 m to 3.5 m.
