摘　　要：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 particularity of driving environment and durability of pavement skid-resistant performance are important factors which influence traffic safety in expressway tunnels. In order to learn about the present situation of pavement skid-resistant performance, mean pavement texture depth （MTD） and British pendulum number （BPN） of one expressway tunnel pavement were measured in different places of this tun- nel. Residual life of its pavement skid-resistant performance was predicted based on surveyed traffic volume. Fuzzy cluster was used to analyze pavement skid-resistant performance. The analysis result showed that the cluster result was in good agreement with the actual situation. This paper provides scientific basis to make reasonable pavement maintenance countermeasures and to define proper speed limitation in tunnels, which will lead to a decrease in or avoidance of traffic accidents. Besides, this paper can also serve as a reference to the whole structure reliability analysis in expressway tunnels.
