在等电势梯度的前提下，针对电渗法加固软黏土地基提出了阳极跟进技术，设计了8组电渗对比试验，对不同阳极跟进方案作用下电渗试验的电流、抗剪强度、排水量、含水率、pH值和土体电导率等指标进行了监测，分析了不同方案下的电渗加固效果。试验结果表明：采用阳极跟进技术时，第1次阳极跟进作用效果最为显著；在电流密度处于高位时进行阳极跟进会在一定程度上降低电渗效率，在电流密度处于低位时进行阳极跟进能够促进电渗作用；针对阴极区土体开展阳极跟进无法获得显著的加固效果。研究结果表明，阳极跟进技术能够降低电路中的阳极区电阻，有效提高电渗加固效果。

Under the equipotential premise gradient ,anode follow-up technical was proposed in the electro-osmosis reinforcement of soft clay . Eight electro-osmosis contrast tests were conducted through the experimental test .Currently ,shear strength ,displacement ,moisture content ,pH ,conductivity of the soil and other indicators were monitored in the electro-osmosis test .Different electro-osmotic reinforcement effects were analyzed .The results show that :when the anode follow-up is used ,the first anode follow-up can get a most significant effect .When the current density is high ,arranging the anode follow-up will lead some extent reduce of the effect of the electro-osmosis ,while the effect will be promoted when the current density is low .By carrying out the anode follow-up on the cathode region soil ,a significant reinforcement effect can be obtained .Anode follow-up can reduce the resistance of the circuit in the anode region and effectively promote the electro-osmosis reinforcement effect .
