It is an effective way to solve the increasingly scarce urban land resources by making a large area of land reclamation through dredging and filling. Based on the actual engineering of dredging and dredging foundation under vacuum combined with water preloading method, based on the real-time observation data of vacuum period, combined with three-dimensional Biot consolidation theory, the modified Cambridge constitutive model is used, and ABAQUS software is used to carry out three-dimensional FEM simulation. The results show that the simulation results are in good agreement with the measured data.%通过疏浚吹填的方式进行大面积围海造陆是解决城市土地资源日益紧缺的有效途径.本文在真空联合覆水预压法加固处理疏浚吹填地基的实际工程基础上,根据抽真空期间现场实时观测的数据,结合三维Biot固结理论采用修正剑桥本构模型,使用ABAQUS软件进行三维有限元模拟计算,结果表明模拟计算结果与现场实测数据曲线拟合较好.
