| 摘 要： | 以发生在G5高速公路雅西段避险车道上的一起交通事故为研究内容,分析避险车道存在的安全隐患.利用PC-CRASH的“车轮-松软路面相互作用模型”对事故避险车道安全性进行评价,并与视频记录的过程进行比较,初步验证了模型和方法的可行性.最后对模型的坡度及沉陷深度参数改进后进行仿真,结果表明,货车以120km/h驶入制动床后经历不到100m距离即可停止.

| Abstract: | With the study of a real traffic accident happening on the truck escape ramp of G5 freeway,the safety of the ramp is analyzed.By the model of wheel-soft soil interaction of PC-CRASH program,the safety of the truck escape ramp is evaluated and compared with the video recording of the accident.The result indicates that the validation of the model is feasible.Simulation results of optimized slope and sinking depth parameters show that trucks driving into the truck escape ramp at a speed of 120 km/h could stop after running less than 100m. |
