ABSTRACT

This paper adopts a residual stress model considering the full size, depth of foundation pit, and the change of stress in the soil after each excavation step to conduct the rebound deformation calculations. Comparing with the theoretical methods and the Plaxis 2D ﬁnite element model, this method not only calculates very simple but also the obtained results are quite similar to the actual monitoring results, making the forecast of rebound deformation of the foundation pit better.

Keywords: Foundation pits; Residual stress; Rebound deformation; Finite element model; Monitoring
