Abstract

Taking the construction of bottomless foundation pit of the East Extension Dou Ge-Zhuang Station of Beijing Subway line 7 as an example, combined with the influence factors of the station`s geographical location, stratigraphic lithology, hydrogeology, and surrounding environment, the surface uplift of bottomless foundation pit of this station is directionally analyzed. According to the data of steel support and monitoring during the construction of the bottomless foundation pit, Midas geotechnical software is used to simulate the overall construction of bottomless foundation pit, and the mechanism of foundation pit uplift is analyzed, combined with the curve of soil mass variation during the simulation process, the solution to surface uplift is proposed, which is of great significance for similar cases of future projects.

Keywords
