摘　　要：隧道底部调平层的施工质量直接影响到洞内路面质量和造价。分析了超欠挖和通车时间对隧底调平层质量、造价的影响。合理选择钻爆工艺是减少超欠挖的关键环节,合理安排调平层混凝土施工车辆通行时间,有利于隧道调平层的质量控制和降低造价。The construction quality of the bottom leveling layer of the tunnel directly affects the quality of pavement inside tunnel and cost.Analyzed the influences of over digging and less digging and traffic time on the quality controlling and cost of tunnel bottom leveling layer.Drilling and blasting process is a reasonable choice to reduce the key.Reasonable arrangements the pass time of concrete construction vehicles for the leveling layer is in favor of quality control and cost reduction for the tunnel leveling layer.
