摘要

一般在大面积吹填场地真空预压一次处理后即急需进行道路建设

但此时地基承载力尚不能满足道路建设的要求

针对这一情况

开发了一种电渗复合真空预压的方法——即将电渗法和真空预压法有机结合起来

发挥各自的优势

是一种有效的软基处理新技术。本文论述了电渗复合真空预压法的原理、设计方案和施工工艺

并且用现场试验分析了地基处理过程中真空度、沉降、侧向变形、孔隙水压力及水位的变化情况

对处理效果进行了评价分析。可为类似工程提供技术参考。

Abstract

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.
