From many influence factors which affected the deformation of foundation pit’s surrounding soils
three main effective factors such as Young’s modulus
dewatering depth and the permeability coefficient had been chosen as the significantly important factors for input in the 2-D FEA model and the behaviors of settlement were then analyzed. Furthermore
by the 2-D FEA model
the effect of the reduction of the surface settlement due to different distances of recharge or the depth of water-sealing was studied. The obtained results verified that the surface settlement and surface differential settlement of the ground surface could be largely reduced by recharging or water-sealing.
