Abstract:

PLAXIS is adopted to simulate the mechanical behavior and deformation of retaining structure for foundation pit in excavating process. In order to reveal the deformation and internal force of surporting structures, the different heaped loads are considered. The analytical results show that there are great differences between the mechanical behavior and deformation of surporting structures on both sides with the same design parameters. So it is necessary to calculate and analyse surporting structures two sides separately while designing the unbalanced foundation pit.Meanwhile, some conclusions are drawn on performance of supporting structures and deformation of foundation pits through the calculation and comparison.

Key words: PLAXIS, excavation, unbalanced heaped load, internal force, displacement
