Abstract: The rock and soil components, hydrogeology and construction influence of foundation pit retaining structure of subway station constructed by cut and cover method is studied, with the construction of foundation pit retaining structure of Ranjiaba subway station on the line 6 of Chongqing subway as an example. Related construction programs and technical treatments are proposed in basic of studying on the application of cantilever retaining wall, board rib retaining wall and pile and board retaining wall. The study shows that foundation pit retaining structure could be well finished under rational organization and scientific and effective construction program. 

Key words: foundation pit, retaining structure, cantilever retaining wall, board rib retaining wall, pile and board retaining wall, subway station, deformation monitoring
