Abstract

A device for testing the effective potential of soil in real time during an electro-osmosis process of soft clay comprises an electrode, wherein one or more potential tester pieces are regularly arranged outside the electrode, an insulating inner bushing is embedded between each potential tester piece and the electrode, and each potential tester piece is connected to a potential probe. A method for testing the effective potential of soil in real time during an electro-osmosis process of soft clay comprises the following steps: assembling an insulating inner bushing on the surface of an electrode, assembling potential tester pieces outside the insulating inner bushing, and connecting the potential tester pieces to potential probes; and vertically driving the electrode assembled with a device for testing the effective potential into soil, connecting the electrode to a DC power source by means of a wire, and electrifying the electrode according to design requirements to carry out electro-osmosis treatment on a soft clay foundation. The device and method of the invention overcome the defect of disturbance of potential probes, inserted into soil around an electrode, on the soil of traditional methods, and avoid errors caused by different locations of the potential probes.
