在电渗固结过程中,由于土体—电极接触面部分脱空,部分电势在电极处消耗,形成电势降现象,导致能耗损失和效率降低。考虑到斜插电极依靠重力作用有利于维持土体与电极间的接触,设计了相关的电渗试验模型,开展了斜插电极条件下的电渗试验,并与垂直电极的电渗试验效果进行了对比,分析了两种电极布置方式下电压降减少量、电流和排水量的变化。结果表明,斜插电极能有效控制电渗过程中的电阻变化,维持电流在有效水平,并在电渗时间相同的情况下,斜插电极比垂直布置电极的电渗排水量大、节省能耗。
During the process of electroosmosis consolidation, part of the potential is consumed at the electrode due to the partial emptying of the soil-electrode contact surface, resulting in a potential drop which leads to loss of energy consumption and a reduction in efficiency. Considering that the obliquely inserted electrode is conducive to maintaining the contact between the soil and the electrode by gravity, a relevant electroosmotic experimental model is designed and the electroosmotic test under the obliquely inserted electrode is carried out, and the effect of the electroosmotic test on the vertical electrode is carried out In contrast, the changes in voltage drop, current and displacement under the two electrode arrangements were analyzed. The results show that the obliquely inserted electrode can effectively control the resistance change during the electroosmosis process and maintain the current at an effective level. With the same electroosmotic time, the obliquely inserted electrode has a larger electroosmotic displacement than the vertically arranged electrode, thereby saving energy.
