摘　　要：介绍基于钢筋电解的电化学软基加固法的原理。通过对复合地基有效应力的分析,假定桩-土间的竖向和切向变形协调、应力平衡,建立用于计算电化学群桩复合地基三维固结的复合有限元模型。考虑桩体模量沿径向线性递减的工况,对一次性加载条件下电化学群桩复合地基的固结情况做详细分析。分析成果表明:经电化学桩法加固后,复合地基的承载力得到明显提升。The principle of soft soil foundation consolidation method on the basis of electrochemical of steel electrodes（ESDS）was introduced.Through the analysis on the effective stress of composite foundation,assuming deformation consistence and stress equilibrium at the interface between piles and soil,the composite FEM model was established to calculate three dimensional consolidation of electrochemical piles composite foundation.Considering.the condition that the modulus of pile is linearly decreased along the radius of pile,the consolidation of electrochemical piles composite foundation under one time loading condition is analyzed in detail.The results show that after consolidation by the electrochemical piles method,the bearing capacity of the composite foundation has been improved obviously.
