Analysis on the Influence of Deep Foundation Pit Construction with Surrounding Environment of Metro Station in Zhongyuan Area

Abstract

The surface settlement, horizontal displacement, supporting axial force, settlement, and stress of the retaining structure in the entire process construction are examined using the deep foundation pit excavation of a metro station in Zhengzhou as a backdrop. The results show that as the foundation pit's excavation depth increases, the retaining wall's maximum horizontal displacement travels downward from the top, and the deformation curve shifts from a comparable cantilever beam to a "bow" curve. The initial reinforced concrete support and retention structure must be protected against breaking due to lateral displacement at the top of the wall. The excavation of the foundation pit causes the surrounding surface to settle. All of the supports are in a safe functioning condition during the foundation pit excavation procedure.
