Study on the Influence of Step-by-step Excavation of Foundation Pit on Supporting Structure

Abstract

Aiming at the influence of step-by-step excavation of foundation pit on the internal force and deformation of supporting structure, this paper summarizes the research status of domestic and foreign scholars on this issue, introduces the calculation method of internal force of supporting structure, and uses GEO5 software and ABAQUS finite element analysis software to solve the internal force and deformation of supporting structure in the process of step-by-step excavation, and compares it with the measured results.
