| Abstract: | The Ganqing Tunnel of Datong-Xi＇ an Passenger Railway cross the water rich and sand strata, which makes it easy to suffer from the flow of sand, sand rush in and mud rush. The construction safety and quality of the tunnel is serious-ly affected. This paper mainly introduces the idea and method of technological solution for the tunnel. Through analysis and comparison, the plan of compensation for underground water level is determined to help recover ground water resources to the greatest degree. |
