利用有限元分析软件 ABAQUS,分别采用小应变理论和大变形理论,对真空联合堆载预压法处理软基进行了仿真和固结分析.根据固结度等效原则,将砂井地基转换成平面应变砂墙地基,将模拟数据与某公路监测段监测数据进行对比,结果表明,用大变形理论处理深厚粘土软基更为合理.

By the ABAQUS software, the process of vacuum-surcharge preloading on soft foundation is simulated, and its consolidation of settlement is analyzed. The simulation during vacuum-surcharge preloading with small deformation theory and large deformation theory are separately computed. According to the principle of equivalence of the consolidation degree, sand-drained ground will be converted into plane strain sand wall foundation. Combined with a highway monitoring segment, the simulation data are compared with monitoring data. Data analysis shows that the large deformation theory on treating deep soft clay was more reasonable.
