通过凉水井隧道进洞的施工实例,对小净距偏压隧道进洞前的明洞开挖、边仰坡防护、超前长管棚、偏压护拱,和进洞过程中的洞身开挖及初支、二次衬砌施工各个环节的总结探讨,并对在施工过程中的监控量测的进行深入研究,从而为类似隧道的施工积累经验。 Through the construction example of Liangshuijing tunnel, we excavate the bright hole in front of the tunnel with small clear distance bias, protect the slope sideways, advance the long pipe shed, protect the arch with bias, and excavate the tunnel body And the first branch, the second lining of the construction of all aspects of the summary of the discussion, and monitoring of the construction process in-depth study of measurement to accumulate experience for similar tunnel construction.
