Study on the Influence of Open-cut Foundation Pit Construction on Adjacent Buildings in Subway Stations
Combined with the actual situation of a subway station project in Nanchang,this paper mainly studies the whole excavation process of open-excavation construction foundation pit in subway station and the influence of different support methods on the stability of nearby buildings within the influence range.Using finite difference software,the whole excavation process of station foundation pit and the change of building displacement are numerically simulated,analyzed and compared.A more reasonable excavation and support method for station foundation pit is selected to ensure the safety of the whole excavation process,reduce the impact of foundation pit excavation on the surrounding environment and adjacent buildings,and ensure the safety of adjacent buildings.Through the successful completion of open excavation construction in this station,various parameters are consistent with the numerical simulation results,which can guide the safe construction of similar subway station projects.
