The authors designed three groups of unsaturated loess electrochemical improvement specimens,and injected differ-ent concentrations of the acidic adjustment solution into the cathodes of three groups of specimens(the concentration of the reg-ulating solution of soil A was 1％～5％,soil B sample was 6％～10％,and soil sample C was 11％～15％).The effect of the concentration of the regulating liquid on the modified consolidation of the electrochemical improvement of the loess samples was discussed through comparative experiments,and the following main conclusions were made by analyzing the current,displace-ment,energy consumption and the improvement strength of different curing ages after the test:(1)Compared with the tradi-tional electrochemical improvement,the injection of the acidic adjustment liquid into the cathode can expand the drainage chan-nel of the loess samples,thereby extending the drainage time and thus improving the reinforcement effect;(2)The higher the concentration of the acidic adjustment liquid,the more the unit energy consumption and drainage;(3)The higher the concen-tration of the acidic adjustment solution,the higher the soil strength after the improvement.
