Abstract

The invention discloses an electro-osmosis consolidation shearing device. The electro-osmosis consolidation shearing device comprises a frame, a vertical loading system, a horizontal shearing loading system and an electric insulation experiment box, wherein the frame comprises a bottom frame and a portal frame; the bottom frame is fixedly connected with the portal frame; the vertical loading system is fixedly connected to the upper wall of the portal frame, and comprises a shaft pressure air cylinder, a shaft pressure displacement electronic sensor and a shaft force sensor; the electric insulation experiment box comprises electrode tubes, an upper shearing box and a lower shearing box; during an electro-osmosis experiment, soil is placed in the upper shearing box and the lower shearing box, and the electrode tubes are inserted into the soil. The electro-osmosis consolidation shearing device is high in experiment efficiency, small in occupation area, convenient to operate, compact in structure, accurate and reliable in determination result, and applicable to an indoor or field experiment for the electro-osmosis test on soft clay and mucky soil in eastern coastal regions and the Pearl River Delta region, and serves for solving the related engineering problems of foundation deformation and stability parameter determination in geotechnical engineering problems of foundation treatment, coastal reclamation, port revetment and the like.

Description

technical field [0001] The invention relates to geotechnical engineering testing technology in the field of civil engineering, in particular to an electroosmotic consolidation shearing instrument. Background technique [0002] At present, there are large areas of saturated soft clay and muddy soil in the eastern coast of my country and the Pearl River Delta. These soils have the characteristics of high moisture content, high compressibility, and low strength. They are used in many civil engineering, water conservancy, port and other related projects. The problem of slow consolidation of foundation or soil drainage is common. In recent years, some people have applied soil electroosmosis combined with surcharge preloading technology to the reinforcement treatment of soft clay foundation, and achieved good results. Practice has proved that this electro-osmotic method can not only increase the consolidation speed of the soil, but also make the soil more dense, and achieve the re...
