| 摘 要： | 通过3组模型试验研究活性炭夹层对电渗过程中两极裂缝进行处理的电渗效果。试验表明:采用活性炭夹层对电渗过程中形成的裂缝进行处理来可改善电渗排水,具体表现为活性炭夹层的加入对于提高土体中水分的排出量、增加土体两端的有效电势、降低土体含水率及降低电极腐蚀有利,且只在阳极附近加入活性炭夹层的土样电渗效果优于在土体两极均加入活性炭夹层的土样。试验结果对电渗固结排水工程有一定参考意义。

| Abstract: | Three laboratory tests program were conducted in order to investigate the effect of double electrode fracture treatment on electroosmotic drainage.It shows that activated carbon treatment for crack is necessary and it can improve the discharge of moisture in soil increase the voltage of the soil at both end reduce the moisture content of soil and lower electrode corrosion. Only add activated carbon interlayer soil samples near the anode electroosmosis effect is better than that of poles are adding activated carbon in soil interlayer soil samples. |

| Keywords: | electroosmosis crack treatment activated carbon sandwich effective voltage electrode corrosion |
