Water content Pore ratio for each load stage Initial state 66.67% 1.586 After initial consolidation 55.8% 1.451 Conducted electroosmotic vertical drainage cylinder experiment 0-6 hours 53.4% 1.388 6-8 hours 52.2% 1.357 8-20 hours 51.4% 1.336 20-24 hours 50.6% 1.315 24-48 hours 50.5% 1.313

From Figure 1 and Tables 2 and 3, the settlement speed is significantly different when the voltage is applied at a constant load and when it is not.

That is, when the electroosmotic pressure was applied to the smear zone 70 through the electroosmotic vertical drainage cylinder test, it was confirmed that the consolidation speed was significantly improved compared to the non-voltage vertical drainage state. This means that the horizontal drainage of the smear zone 70 to which the electroosmotic pressure is applied is improved, and the permeability of the smear zone 70 can be improved by using the electroosmotic pressure.

The present invention configured as described above can increase the ground strength as desired by the user by appropriately applying the electroosmotic pressure, and by advancing the consolidation in advance to prevent or allow the consolidation settlement that may occur due to the structure to be placed on the ground after the ground improvement. It is limited to within the range, by improving the permeability of the smear zone 70 is to minimize the cost and time required to improve the overall ground to be able to achieve rapid consolidation.
