| Abstract: | Stratum of the tunnel project of Nanjing Yangtse River is very complex.The diameter of boring machine is very big.The pressure of earth and water in the tunnel is up to 0.75 MPa.The tunnel is excavated by a boring machine which controls and adjusts pressure by slurry-bubble-cushion.The length of tunnel excavated in only one direction by boring machine is 2.9 km.This article introduces many engineering difficulties in the construction and the selection of proper boring machines to excavate the tunnel. |
