通过室内试验研究了软土电化学加固中在阳极分别注入等量纯水和Ca Cl2盐溶液时的不同规律,从电流、排水量、排水速率、能耗、单位能耗排水率及土体承载力等方面对电渗法和电化学法进行了对比分析。结果表明:电化学加固软土时注入的化学浆液能大幅提升电流强度,且电流增幅期持续时间更长;电化学法极大地提升了土体中水的排出量,排水速率与电流大小及土体含水量有关;电化学法具有较高的单位能耗排水效率。通过试验研究,有助于认清电化学法的排水能力及其与电渗法的区别。
The different regularities of injecting the same amount of pure water and CaCl 2 salt solution into the anodes were studied through laboratory tests in terms of current, displacement, drainage rate, energy consumption, energy consumption per unit discharge rate and soil bearing capacity And other aspects of electroosmosis and electrochemical methods were compared. The results show that the chemical slurry injected into the soil can greatly enhance the current strength and the duration of the current increase period is longer. The electrochemical method greatly enhances the water discharge, drainage rate, current and soil Body water content; electrochemical method has a high energy consumption per unit drain efficiency. Through experimental research, help to recognize the drainage capacity of electrochemical method and its difference with the electroosmosis method.
