Effect of electrode spacing on standard electro-osmotic dewatering

  • 摘要: 利用室内试验,研究了两种不同电极距对黏土的水平电渗排水规律的影响,从电渗排水量、排水速率、有效电势、能量消耗、阳(阴)极接触电阻方面等对黏土电渗特性进行对比分析。结果表明:减小电极距在一定时间内能够加快电渗排水速率,可以降低阳(阴)极接触电阻,减小电势损失;电渗排水速率与有效电势成正比,而单位耗能量与有效电势成反比。通过对这些规律的研究,有助于我们更好地认识和掌握黏性土水平电渗排水的规律,为解决富含水的黏性土边坡排水问题奠定基础。
    Abstract: A laboratory test program is conducted to investigate the effect of two different electrode spacings on the standard electro-osmotic drainage of clay. From the aspects of the volume of electro-osmotic drainage, rate of electro-osmotic drainage, energy consumption, effective voltage and contact resistance, two tests are compared to analyze the electro-osmotic characters of clay. The results show that decreasing the electrode spacing can improve the rate of drainage in certain time, lower the contact resistance and reduce the voltage drop, moreover, the rate of electro-osmotic drainage is proportional to the effective voltage, while the energy consumption is inversely proportional to the effective voltage. With the above studies, it is significant for us to understand and master the rules of standard electro-osmosis drainage of clay and it also lays a better basis on resolving the drainage problems of clay slope which is rich in water.
