摘要
为了给湿热地区隧道路面结构选型和养护决策提供科学依据,在对广东省83座隧道的工作环境、路面类型、路面横向力系数调查研究的基础上,分析了隧道路面抗滑性能衰减的主要原因。结果表明:相对沥青路面,隧道内水泥路面的横向力系数衰减更快;隧道越长、水泥路面抗滑性能衰减越快。隧道水泥路面抗滑性能衰减的原因主要与隧道内的特殊环境有关,同时与交通量、施工质量、原材料等有很大的关系。
In order to provide a scientific basis of pavement structure selection and maintenance decision for hot and humid regions tunnels, being based on the investigation of the working environment, the type of toad surface and the lateral force coefficient of the 83 tunnels in Guangdong Province, the main reasons for the anti-sliding performance of the tunnel have been analyzed. The results have shown that the relative transverse force coefficient of asphalt pavement in tunnel cement concrete pavement decay faster; when tunnel is longer, the anti-slide performance attenuation of ceroent concrete pavement becomes f;tster; the anti-slide perfor- mance degradation of cement concrete pavement of tunnels is mainly connected with the specific environmental conditions of the tunnel, as well as with the traffic volume, construction quality and raw materials.
