It is a complicated nonlinear procedure to calculate the deformation against upheaval of deep foundation pit

because the factors affecting the deformation are fuzzy and random.However

the finite element analysis is an effective method to solve the problem.Based on the finite element software ABAQUS

in this paper

the heave deformation of deep foundation pit for some subway in Shanghai is analyzed.The study shows that ABAQUS has powerful capacity to analyze the contact problems in geotechnical engineering

and the Maximum deformation appears in a certain region which is not beyond the circle with radius equal to the depth of SMW pile from the wall of the deep foundation pit.The study can provide valuable reference for quantitative heave analysis for deep foundation pit.
