摘要:
为了缓解雨雪气象条件下桥隧连接段的交通安全运行问题，采用Carsim仿真分析软件，建立车辆道路三维模型，通过侧向偏移量和横摆角速度2个评价指标，系统地模拟分析雨雪气象条件下C级标准车在桥隧连接段行驶的稳定性，定量分析行车速度、路面摩擦因数、圆曲线半径对桥隧连接段行车稳定性和车辆横向稳定性能的影响。研究结果表明：侧向偏移量与横摆角速度对行车稳定性的评价具有一致性，当侧向偏移量和横摆角速度指标的值越小、越稳定，车辆行驶越安全；车辆速度与行车稳定性呈负相关，路面摩擦因数和圆曲线半径与行车稳定性呈正相关，即降低车速、增大路面摩擦因数和圆曲线半径均可有效地减小车辆的侧向偏移量。在雨雪气象条件下桥隧连接段的特殊行车环境下，车辆设计速度由80降低至75 km/h，降低了6.25%；路面摩擦因数增大至0.21、圆曲线极限最小半径由250增至265 m，增大了6%；〖JP2〗二者均可保证车辆不发生大幅度侧滑，并能提升车辆行驶的稳定性和安全性，可为山区高速公路设计规划和交通运营管理提供参考。
Abstract:
To ease traffic safety operational problems of a bridge and tunnel connection segment under rain and snow conditions, Carsim simulation analysis software was used to establish a threedimensional vehicleroad model. Using the two evaluation indexes of lateral offset and yaw rate, the driving stability of a class C standard vehicle along the bridge and tunnel connection segment under rain and snow conditions was systematically analyzed. Then, the influence of vehicle speed, road friction coefficient, and road circular curve radius on the operational and lateral stability was quantitatively analyzed. The results show that the evaluation of vehicle stability by lateral offset and yaw rate is consistent. The smaller and more stable the value of lateral offset and yaw rate, the safer the vehicle driving. The vehicle speed is negatively correlated and the road friction coefficient, and the circular curve radius are positively correlated with the driving stability. In other words, decreasing the vehicular speed and increasing the road friction coefficient and road circular curve radius can effectively reduce the vehicle lateral offset. Under the special driving environment of a bridge and tunnel connection segment under rain and snow conditions, the design speed of the vehicle is reduced by 6.25% (from 80 to 75 km/h,), the road friction coefficient increases to 0.21, or if the minimum circular curve limit radius increases by 6% (from 250 to 265 m), the vehicle is not subject to sharp side slip, and the stability and safety of vehicles is improved. This study provides a reference for mountain highway design and traffic operational management. 1 tab, 21 figs, 22 refs.
