Electric vertical drains (electrokinetic geosynthetics with filtration, drainage, reinforcement, and electrical conductivity function) have been used as electrodes and vertical drains in the treatment of soft clay by vacuum preloading combined with electroosmosis. A series of laboratory model tests was performed to investigate the possibility of optimizing the electroosmosis approach in terms of effectiveness and energy efficiency. The results show that the vacuum preloading and electroosmotic approaches have counteracting effects in the vicinity of the electric vertical drain anode when they are used simultaneously. By alternating the vacuum preloading and electroosmosis approaches, the dewatering process becomes more effective and energy-efficient.

电动垂直排水管（具有过滤、排水、加固和导电功能的电动土工合成材料）已被用作真空预压结合电渗处理软粘土的电极和垂直排水管。进行了一系列实验室模型测试，以研究在有效性和能源效率方面优化电渗方法的可能性。结果表明，真空预加载和电渗方法在同时使用时在电垂直漏阳极附近具有抵消作用。通过交替使用真空预加载和电渗方法，脱水过程变得更加有效和节能。
