基于路面抗滑性能的隧道行车安全分析

采用路面抗滑性能测试车SCRIM 3000对广东某高速公路7座隧道段路面横向力系数进行测试,得到隧道段路面横向力系数分布规律,即隧道外的路面抗滑性能普遍优于隧道内路面;同时结合其近几年隧道交通事故的统计分析研究了隧道段路面抗滑性能与交通事故的相关关系,得到隧道段路面抗滑能力不足和其出入口内外路面抗滑性能差异过大是影响隧道行车安全的重要因素。

Driving Safety Analysis for Tunnels based on Anti-slide Performance

The lateral force coefficients of seven tunnel pavement have been tested using pavement anti-sliding performance test car SCRIM 3000, and the distribution law of the lateral force through the tunnels pavement has been obtained, which shows that the anti-sliding performance outside the tunnel pavement is better than that of inside tunnel pavement. Considering the statistical analysis of tunnel traffic accidents in recent years, the relationship between the anti-slide performance and traffic accident has been studied, which showes that it is the lower anti-slide performance of tunnel pavement and the difference of anti-sliding performance between inside and outside of tunnels that has become an important factor affecting the safety of tunnel driving.
