| Abstract: | No.2 karst cave of Yuanliangshan Tunnel on Yu Huai railway is located in the Maoba syncline section where there exists rich high pressured water. The longitudinal width of the level profile of No. 2 karst cave is 50m. The water pressure measured under the condition of partial water discharge is 3.013 MPa. Furthermore, the karst cave contains a large amount of fine silt sand. The emphasis of the article is placed on the introduction of the excavation technology adopted in the full face breakthrough of No.2 karst cave section of the tunnel. |
