Abstract: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.
Keywords:highway tunnel  environmental protection  hangar tunnel  pseudo portal  post-covering excavation
