Shear test loading device for geological survey

The utility model relates to a shear test loading device for geological survey. Its technical scheme is: cut the box under install on the upper portion of base, the upper portion of cuting the box under is installed and is cuted the box, and cut under and be equipped with the displacement graduation apparatus between box and the last shearing box the left side lower part fixed mounting of grudging post has the horizontal hydraulic jack, has perpendicular hydraulic jack at the top?Middle fixed mounting of grudging post, is equipped with the vertical load manometer on the perpendicular hydraulic jack, the base on be equipped with the slide rail, the left side of cuting the box on is equipped with the arch, the grudging post on be equipped with the vertical guide groove. The beneficial effects of the utility model are that: the device can provide the intensity parameters of rock under different normal direction tensile force, is drawing the constitutive relation and the intensity criterion of cutting the stress
