Study on the Deformation Law of Foundation Pit with Shared Ground Connecting Walls

Abstract

This study comprehensively investigates the mechanical behavior and deformation patterns of adjacent foundation pits sharing a common ground connecting wall. Utilizing a combination of detailed field measurements and finite element modeling, the study simulates the excavation process to analyze the mutual interactions between two adjacent pits of equal depth. Results indicate that the excavation of a subsequent pit influences both surface settlement and the horizontal displacement of the retaining structure of the first-excavated pit. Specifically, the surface settlement outside the first-excavated pit increased by 0.08% H
