摘　　要：针对长距离隧洞中Ⅱ、Ⅲ类围岩区段仅施作路面混凝土,Ⅲ(围岩特殊段)、Ⅳ、Ⅴ类围岩区段进行全断面钢筋混凝土衬砌的隧洞,且地质围岩分布不均且不连续,同时施作路面混凝土区段的占比较大。为了解决深埋长距离隧洞路面混凝土衬砌高断点的问题,加快长距离隧洞路面混凝土的施工进度,针对分布不均、不连续性、隧洞占比大的长距离隧洞路面混凝土快速施工方法的操作要点、相关管控措施等进行研究。For tunnels with Class II and III surrounding rock sections in long-distance tunnels,only pavement concrete is applied,while Class III(special section of surrounding rock),IV,and V surrounding rock sections are lined with full section reinforced concrete.The geological surrounding rock distribution is uneven and discontinuous,and the proportion of pavement concrete sections is relatively large.In order to solve the problem of high breakpoints in the concrete lining of deep buried long-distance tunnels and accelerate the construction progress of long-distance tunnel pavement concrete,research is conducted on the operation points and related control measures of rapid construction methods for long-distance tunnel pavement concrete with uneven distribution,discontinuity,and a large proportion of tunnels.
