| Abstract: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. |
