摘要
向家隧道是大岳高速公路一条短隧道。尽管较短,但其洞口存在大偏压,且边仰坡围岩为全风化花岗岩,因而是一个关键性控制工程。文章对向家隧道进洞方案进行阐述,力求为隧道施工提供技术支持。
Xiangjia Tunnel is a short tunnel in Dayue Expressway.Even if it is short,but there is a big bias in the entrance,and the surrounding rock of the side and face upward slope is weathered granite,so it is a key control project.Entrance scheme of Xiangjia Tunnel is briefly summarized in this paper, it will provide some useful guidance for tunnel construction.
