摘　　要：结合上海某临港新城大面积吹填土地基处理工程,对真空降水联合低能量强夯加固大面积吹填土路基进行研究,对加固过程中及加固后的地下水位变化、超静孔隙水压力变化、工艺参数、以及加固机理进行分析和讨论。在此基础上确定大面积施工的参数和工艺。真空降水联合低能量强夯的技术进一步拓宽了井点降水和强夯法的适用范围,为我国沿海地区工程建设中遇到的大面积吹填土加固问题提供新的途径。During the treatment of dredger fill roadbed with soft clay intercalation in a new city of Shanghai,a new idea of dynamic consolidation method(DCM) combined with well dewatering technique was proposed.Through the analysis of the variation of underwater level,pore pressure and the technology parameter,the mechanism of this new method applied to the dredger fill with soft clay intercalation was discussed.All the results show the feasibility of DCM combined with well dewatering in the treatment of dredger fill with soft clay intercalation and enrich the contents of the DCM and well dewatering technology,which also proposed a new method for the treatment of the large-area dredger fill in the coastal areas.
