Abstract: The numerical simulation of the deformation character in the effect of the unloading action for the surcharge preloading in the heap preloading treated foundation in the Sixin South Road in the New District in Wuhan is done through the finite element analysis software ABAQUS according to the engineering project ,and the following conclusions are gained:(1)on the surface of the foundation, the settlement at the center is the biggest, the settlement decreases with distance from the center of the surface, ,and at about 20m away from the center, the uplift is produced ;(2)after unloading, the resilience emerges in the places where the settlement was produced, and the uplift that was produced drops too;(3)the deformation on the axle of the foundation section at the end of the loading action and that at the end of the unloading action are similar to each other;(4) in the step loading-unloading condition, the deformation curves suit well with the loading-unloading curves.
