摘要:

主要介绍永武高速龙井隧道施工中,针对采空区段隧道施工采取双层小管棚超前支护,喷锚封闭,泵送混凝土回填,隧道洞身加强支护和设置缓冲层和施工监控量测等技术措施,使隧道施工安全稳妥地通过采空区地段,为今后此类地质条件下的施工提供了借鉴经验。

Abstract:

During the construction of Longjing tunnel on Yongwu highway, technical measures such as advance support by means of double layers of small pipes, sealing by shotcreting and rock bolting, backfilling by pumped concrete, enhanced support of tunnel body, installing cushion layers and monitoring measurement are taken for the minedout area. In the end, the tunnel passes the minedout area safely and successfully. These technical measures are presented in the paper, which can provide reference for similar works in the future.
