摘要
结合吉青岭隧道的工程实际,分析了浅埋偏压不良地质条件下隧道进口段的施工风险,提出了采取初期支护加强,短循环开挖,初期支护封闭等综合地质病害预防措施。
Based on the engineering case in Jiqingling tunnel, risk analysis was made on the construction of tunnel entrance in poor geological condition with shallow-buried and unbalanced pressure. Integrated prevention measures for geological diseases were put forward with early support strengthening, short cycling excavating and early support closing.
