摘要
以三导坑先墙后拱法及中导坑辅助法在湖南吉怀高速公路龙子康隧道施工中的应用为例,系统地研究了不同围岩级别及地质情况下连拱隧道的施工方法、施工工序、施工注意事项、监控量测等技术问题,为连拱隧道施工提供有效指导.
Taking the construction in Longzikang tunnel of expressway Jishou-Huaihua of Hunan by triple heading and first on both sides and then on top method as well as mid heading-assisted method as an example,some technical problems of twin-arch tunnel under different levels of rock and geological circumstances are studied systematically,such as construction method,construction procedure,construction cautions and monitoring measurement.They can provide effective guidance for the construction of twin-arch tunnel.
