隧道洞口浅埋段是隧道施工的薄弱环节,施工不当,就会导致变形过大、整体下沉,甚至通天冒顶,因此,选用切实可行的进洞方案对保证隧道施工安全和快速进洞有着重要意义,本文详细介绍采古隧道进口穿过浅埋段土石坡积体的施工技术,为类似隧道施工提供参考。
The shallow section of the tunnel entrance is the weak link in the construction of the tunnel. Improper construction can lead to excessive deformation, overall sinking and even overhead roof collapse. Therefore, choosing a feasible hole solution is important for ensuring tunnel construction safety and quick hole penetration Significance, this article introduces in detail the construction technology of the entrance of ancient mining tunnels through the shallow buried soil and stone slope, providing reference for similar tunnel construction.
