行车环境的特殊性和路面抗滑性能耐久性是影响高速公路隧道交通安全的重要因素.为了解路面抗滑性能现状,以某高速公路隧道路面为研究对象,实测道路交通量和隧道路面不同位置平均构造深度MTD和摆值BPN.预估了隧道路面抗滑性能的剩余寿命,并用模糊聚类分析方法对数据进行处理,得到隧道不同路段路面抗滑水平聚类结果,分析结果与实际状况吻合.为制定路面养护对策、进行合理的车速管制提供了科学依据,减少或避免交通事故的发生,也为高速公路隧道路面整体可靠性评价提供参考.
The peculiarity of driving environment and the durability of pavement slip resistance are the important factors affecting the traffic safety of expressway tunnel.To understand the status quo of pavement slipperiness performance, taking a highway tunnel pavement as the research object, the measured traffic volume and the location of tunnel pavement The average depth of construction MTD and the swing value BPN.The estimated residual life of the anti-sliding performance of the tunnel pavement and the fuzzy clustering analysis method to process the data to get the anti-sliding level clustering results of the pavement of different sections of the tunnel are consistent with the actual situation In order to formulate the road maintenance countermeasures and provide a scientific basis for reasonable speed control, the occurrence of traffic accidents can be reduced or avoided, and the overall reliability evaluation of highway tunnel pavement can be provided as reference.
