| Abstract: | The geological and hydrological conditions of the tunnel project are introduced in the paper. The difficult points are analyzed. The auxiliary measures of densely inserted reinforcing steel bar and laying barbed wire and deep hole drainage are raised on the base of the conventional supported measures of advanced grouting small steel pipe and sprayed concrete and steel arch shelf, with the guidelines of eighteen words for shal- low-underground tunnels, the rich-water sand layer is smoothly excavated. |
