摘　　要：为了揭示电化学方法加固超软土的加固机理,将外接电压、异性极距和同性极距等试验参数作为影响因子,设计正交试验方案,进行了超软土现场电化学加固试验,并获得了最佳加固试验参数。基于电化学原理和现场测试的实时数据分析,揭示了电化学加固过程的动态变化规律,并给出电化学加固过程的能耗系数表达式。In order to reveal the mechanism of electrochemical consolidation, field test is conducted to study the process of electrochemical consolidation of ultra-soft soil. The orthogonal experiment method is adopted to analyze the influence of the parameters which is external voltage, homopolar distance and heteropolar distance. Based on the analysis of real time data, the principle of electrochemistry is introduced to discuss the dynamic change rule of electrochemical consolidation. At the same time, this paper also gives the expression for the energy coefficient of electrochemical consolidation.
