| Abstract: | The horizontal displacements are monitored during excavation procedure in the sidewalls of Fuxingmen Station, a returning tunnel of Beijing Subway buried in soil media. Based on these results with those obtained from other engineering projects, the characteristics of horizontal displacement are analyzed in shallow soil tunnels during grouting and excavation procedure of the tunnels. The usage of inclinometer for construction monitoring is studied primarily, and a new underground construction method in soil media, i.e., grouting prior to NATM construction is assessed. |
