Finite Element Analysis on Lateral Deformation of Foundation Pit Influenced by Prestress of Fish-Bellied Beam Support

Abstract:

The problem of loss of prestress and compensation of prestress of Fish-Bellied Beam Support exist in foundation pit construction but seldom be considered in design. Finite Element Analysis on an existed foundation pit engineering of prestressed Fish-Bellied Beam Support by using finite element software ABAQUS. Discussed the influence on lateral deformation of foundation pit caused by loss of prestress and compensation of prestress.The results show that the influence on lateral deformation of foundation pit caused by loss of prestress and compensation of prestress is remarkable, and existing a critical loss percentage, lateral deformation of foundation pit will be well controlled by adjusting compensation of prestress in terms of considering the critical loss percentage.
