高速公路隧道环保型建设技术

摘要

宁（南京）淮（淮安）高速公路老山隧道右线出口采用傍山棚洞结构,隧道进洞采用假拟洞门方法;宁（南京）常（常州）高速公路茅山西隧道超浅埋段采用盖挖法施工。实践证明,以上三种施工方案,不仅保证了施工安全和工程质量,而且大幅度减少了山体土石方开挖,充分保护了隧道周边的自然生态环境,取得了很好的环保效益。%The design of the exit section of the right line of the Laoshan Tunnel of the Nanjing-Huai′an Highway adopts the structure of a hangar tunnel alongside the mountain.The entrance section of the Laoshan Tunnel is of a pseudo portal.The super-shallow section of the Maoshan West Tunnel of the Nanjing-Changzhou Highway is dug by the post-covering excavation method.Practice proves that the three above-mentioned construction schemes can not only ensure the safety in construction and the good quality of the project,but also greatly reduce the amounts of earthwork and stonework to be removed,which helps sufficiently safeguard the surrounding natural environment and thus obtains very good benefits in environmental protection.
