利用有限元软件对一分期堆载预压法加固的软基进行了数值模拟，预估了一级堆载的高度，分析了软基土体由于堆载而产生的初始破坏部位、塑性变形区域、位移沉降、应力、应变等，据此指导后期堆载过程中的监测，确保地基的稳定和堆载的安全。

Finite element software is used to carry out numerical simulation against the soft foundation reinforced by the first stage of preloading. With the estimation of the height of a stage of loading, the initial failure part at the soil mass of soft foundation caused by loading, and the plastic deformation region, subsidence and displacement, stress, strain thereof are analyzed to guide the supervision in the later loading process and ensure the stable foundation and safe loading.
