摘要
隧道洞口施工一直是隧道工程的一个难点,也是暗洞正常施工的前提。首先阐述了隧道施工的地形、地质、气象和周边环境,然后提出进洞施工的一系列方案,希望可以实现安全进洞,保证安全施工。
Tunnel opening construction is always a difficult point in tunnel engineering.It is also a prerequisite for the normal construction of a dark tunnel.First,the topography,geology,meteorology and surrounding environment of the tunnel construction are expounded.Then,a series of plans for the construction of the tunnel are put forward,so that safe access can be realized and safe construction can be guaranteed.
