根据对我国隧道施工的经验,从隧道洞口段的设计、施工和支护的角度出发,在坚持隧道施工原则的条件下,提出了隧道洞口段施工的支护方法,包括喷射混凝土、锚杆支护、挂钢筋网和刚支撑等方法。采取有效的支护方法及必要的辅助施工措施,同时加强施工管理,科学合理地组织施工,才能达到隧道洞口段施工支护的预期目的。
Based on the tunnel construction in China,and considering design,construction and supporting at the tunnel entrance,the paper,standing by the principles of tunnel construction,proposes some supporting methods,including gunite concrete,rock bolting,mesh reinforcement and just supporting.Only effective supporting,necessary construction measures,strengthening of management and scientific and reasonable organization can achieve the intended goal of supporting.
