Abstract:

The station presented in this paper is in the finesand layer, and passes through the heating, water, sewage and gas pipeline, and is in close proximity of some important buildings, therefore, controlling the settlement of ground during the construction of the station become very crucial. The techniques and measures in the construction of the threearch shallow station are discussed. The tunnelcolumn method is used to reduce the settlement and ensure the safety. In addition, the reasons of settlement and its distribution system during the construction of the largescale tunnels in urban areas are analyzed.

Key words: mining method threearch station, tunnelcolumn method advance explore changing support optimization of schemes
