高速公路隧道进出口段路面抗滑性能与交通安全分析

Analysis on Pavement Antiskid Property and Traffic Safety at Entry and Exit Sections of Expressway Tunnels

分析了广东省内43座高速公路隧道技术参数及路面结构形式,采用横向力系数测试车(SCRIM)对隧道的进出口段进行抗滑性能检测,并对隧道进出口段横向力系数分布和交通事故进行分析,结果表明隧道进出口路面良好的抗滑性能可以有效减少交通事故。

Through analysis on technological parameters and type of pavement structures of 43 expressway tunnels in Guangdong Province, antiskid properties of entry and exit sections of tunnels have been tested with Sideway-force Coefficient Routine Investigation Machine （ SCRIM） , and analysis on sideway-force coefficient distribution and traffic accidents at entry and exit sections of tunnels has been conducted, the results show that excellent pavement antiskid properties at entry and exit sections of tunnels can effectively reduce traffic accidents.
