摘　　要：利用交通事故再现软件PC-Crash,提出了一种具有动力学响应输出的避险车道事故三维仿真方法。该方法使用经典的贝克理论作为模拟制动床集料特性的理论模型。详细提供了利用PC-Crash再现避险车道事故的7大步骤,讨论了其中的关键问题;给出了不同参数组合下避险车道制动床所需长度的试验结果,最后介绍了一个工程应用案例。此方法主要用于直观、定量地测试避险车道的坡度、长度、集料特性等参数,或三维再现具体的避险车道事故过程。A three-dimensional kinetics simulation method of truck escape ramp was put forward based on accident reconstruction software PC-Crash the method uses classical Bekker theory to model the characteristics of arrester bed. Seven main steps of the method were provided detailedly, and the key issues were also discussed. Besides, a set of test results about the length of escape ramp under different parameter combination was received based on the new method; finally, an application case was introduced. The new method mainly used for testing the slop, length, and arrester bed in intuitional and quantitative way; it can also be used for 3D-reconstructing accidents happened in the escape ramp.
