In order to solve the problem of high water content soft soil drainage and consolidation difficulty and long period,electroos-motic tests were carried out with different materials and shapes of electrodes,and the electroosmotic drainage effects of different carbon nanomaterials were compared.The results show that the electroosmotic drainage effect of copper electrode is the best,followed by alu-minum electrode,while iron electrode and stainless steel electrode are relatively poor.The larger the contact area between the electrode and the soil,the more electric seepage water;For metal electrodes of different materials,too much or too little carbon nano-content is not conducive to improving the electroosmotic effect,and there is an optimal value.For copper electrode,the optimal amount of carbon nano-materials is about 0.04%.And for stainless steel electrodes,the optimal value is about 0.08%.
