摘　　要：该室内试验,主要用于研究非饱和黏性土水平电渗排水的规律。通过实验,对电渗排水量、电势、电流等进行了测试,并给出了阳(阴)极接触电阻、阳(阴)区域平均电阻、土体平均电阻的变化规律。通过对这些规律的研究,有助于我们认识和掌握非饱和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。The indoor experiment is conducted to investigate the law of standard electro-osmosis drainage of unsaturated clayey soil. Through the experiment, water yield, electric potential, electric current, the temperature of soil and the like are monitored and surveyed. Based on the data, the changing regularity of several parameters, including the cathode and anode contact resistance, the average resistance of cathode and anode areas, the average resistance of the soil are deduced and calculated. With the study of the regularity, it is beneficial for understanding and mastering the law of standard electro-osmosis drainage of unsaturated clayey soil and laying the basis on resolving the drainage problems of clayey soil slope full of water.
