Electrical Properties of Consolidation of Soft Soil by Vacuum Preloading Combined with Electrokinetics
Electrokinetics in combination with vacuum preloading has obtained good effect on consolidation of soft soil. Experimental studies on changes in electrical properties are conductive to optimize parameters and evaluate the effects of consolidation. Three control experiments are conducted to compare the effectiveness of vacuum preloading combined electro-osmotic strengthening and vacuum preloading combined electrokinetics strengthening
as well as investigating the effect of CaCl
2
injection at different time on experimental effects. The experimental results demonstrate that CaCl
2
injection can increase the current in soil
improve soil conductivity
lower the resistance between electrodes and interface
improve the drainage rate and decrease energy consumption
thereby improving the consolidation effectiveness. The injection way plays a significant role on experimental effect. Appropriately adding a single injection dose can accelerate drainage and choosing the appropriate time period and injection method can effectively control energy consumption and increase efficiency.
