| Abstract: | With the project of the Jiupu Tunnel as a practical example,and upon the basis of analyzing the properties of metamorphic rock,the technical measures regarding the advanced geological drilling,excavating,supporting and retailing,slip-casting to stop water,draining,and water-proofing during lining for the present tunnel across the fault and broken zone are dealt with in the paper,which may serve as a useful reference for tunnels of the same type to cross fault and broken zones in a safe way and reasonable progress. |
