Large-area reclaimed land is in urgent need of municipal road construction after first-stage foundation treatment by vacuum preloading.In view of the bearing capacity of foundation soil can′t meet the requirements of road construction

the authors exploited vacuum preloading-electroosmosis consolidation method

which uses vacuum preloading in combination with electroosmotic consolidation to deal with dredged soft soil.Vacuum preloading-electroosmosis consolidation method is worthy of popularization for it can give full play to the advantages of vacuum preloading and electroosmosis.This paper introduces the mechanism

design method and construction technology of this method and analyses the possible problems of specific technical operations through field test that provide important reference to the follow-up similar project.The vacuum degree

settlement

lateral deformation

pore water pressure and water level were analyzed in the field test in the process of foundation treatment.The evaluation and analysis on the treatment effect verified this method has some applied value in engineering.
