摘要
针对隧道洞口车辆安全状态具有非线性、模糊性和强耦合性,提出了基于熵技术的隧道口车辆安全状态模型及演化机理研究。系统分析隧道口车辆安全状态影响因素,构建了基于信息熵的车辆安全状态评价集,给出隧道口车辆安全状态的熵流模型及其熵值计算方法,研究隧道口车辆安全状态的演化机理。最后以安徽省六武(六安武汉)旺竹园二号隧道洞口事故为例,验证模型的合理性和可行性。结果表明,模型计算结果与实际情况相符,采用熵技术能够揭示隧道口的车辆安全状态演化趋势,为动态车辆安全状态评价提共了新思路。
Aiming at tunnel entrance vehicle safety state with nonlinear,fuzzy and strong coupling,the paper puts forward the model based on entropy technology state of vehicle safety and evolution mechanism research.Through system analysis state of vehicle safety factors,constructed of vehicle safety state evaluation was set based on information entropy and the tunnel traffic safety state of entropy flow model and entropy value calculation method were given,Tunnel traffic safety status of the evolution mechanism was researched.In the last,through analyzing the accident of tunnel entrance in Liuan-Wuhan expressway,the rationality and reliability of this method were verified.Research shows that the model is in line with objective reality and the evolution trend of vehicle safety state of tunnel entrance can be revealed by entropy technology.It provided a new way of thinking for the dynamic state of vehicle safety evaluation.
