Description
Technical field [0001] The invention belongs to the technical field of civil engineering, and relates to a test device capable of simultaneously conducting research on soft clay electroosmosis drainage reinforcement and electroosmosis injection of salt solution to reinforce soft clay, and a test method of the device. Background technique [0002] Electro-osmosis reinforcement of soft clay is divided into two directions: electro-osmosis drainage reinforcement and electro-osmosis injection of salt solution reinforcement. The electroosmosis drainage method is to pass direct current into the soil to be reinforced, and achieve the effect of drainage and consolidation through the action of electric field. Because the drainage rate is fast and has nothing to do with the size of the clay particles, the essence of its consolidation is to generate negative pore water pressure in the soil, and there will be no foundation instability due to the low strength of the soil. More and more attent...
