Abstract
Aimed at the deficiency of traditional method which can't consider ground local load in the cal-culation of heave-resistant stability of foundation pit,This paper set up a method to calculate the safety factor with the consideration of ground local load based on arc slipping method and Boussinesq equation. It also established a numerical analysis model which considers plasticity and strain hardening characteris-tics of soil so as to analyze lateral deformation of retaining structure of foundation pit. The results shows that the safety factor and lateral deformation of retaining structure change significantly when the ground lo-cal load on is assumed to act on the upper part of the sliding mass, which should be paid more attention to in project.关键词
