Numerical Analysis of Deep Foundation Pit Excavation under Complex Beam Support

Abstract

With the deepening of people’s understanding of foundation pit engineering, people pay more and more attention to the three-dimensional characteristics of foundation pit engineering, and the continuous development of computer technology makes it possible to carry out complex three-dimensional finite element analysis of foundation pit. The three-dimensional space finite element of foundation pit is a whole structure that regards all supporting systems and vertical retaining structures as a coordinated work, which can simulate various construction conditions and calculate the internal force and deformation of each component under each working condition. This whole calculation method can also take into account the influence of the deformation of the previous working condition through the life and death technique of the unit, so that the calculation model is basically consistent with the actual situation.
