Considering the existing calculation methods’ shortcomings of water gushing in foundation pit. The strain dependent modi?ed Cam-clay (SDMCC) model adopted to model the soil behavior and confined water was taken into account in the finite difference model by FLAC3D. With the increase of the confined water head (Hw)
the foundation pit heave was divided into three stages: slow uniform deformation
accelerating deformation and sharp uniform deformation. A new method for determining critical water head (Hwcr) of water gushing in foundation pit was presented based on numerical analysis; and the calculation result of the new method was compared with other methods.
