Embodiment Construction

[0038] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0039] Such as figure 1 As shown, the fixed frame 1 is a frame structure, and the four corners of the bottom of the fixed frame 1 are equipped with anchor bolts. A lower positioning plate 2 is arranged on the top of the fixing frame 1, and the lower positioning plate 2 is preferably rectangular and located on a horizontal plane. Directly above the lower positioning plate 2 is provided with an upper positioning plate 4, and the upper positioning plate 4 is also preferably rectangular. The reaction force column 3 is connected, and the reaction force column 3 is perpendicular to the upper positioning plate 4, and the upper and lower ends of the reaction force column 3 are locked with the corresponding positioning plate by nuts.

[0040] Such as figure 1 , figure 2 As shown, a pedestal is fixed at the center of the top surface of the lower positioning plate ...

Abstract

The invention discloses a visualized triaxial test system. The visualized triaxial test system is characterized in that oil is supplied to a transparent pressure chamber (5) through a manual pump (17); a hydraulic cylinder (7) is arranged right above the transparent pressure chamber (5); oil is supplied to the hydraulic cylinder (7) through a variable plunger type hydraulic pump (34); a loading head (8) is arranged at the lower end of a piston of the hydraulic cylinder (7) and faces a pressing rod of the transparent pressure chamber (5); a linear differential transformer (9) is arranged right above the hydraulic cylinder (7), and a probe of the linear differential transformer (9) is contacted with the upper end of the piston of the hydraulic cylinder (7); four cameras (11) and three video cameras (12) are arranged on the periphery of the transparent pressure chamber (5). The visualized triaxial test system is simple and compact in structure, convenient to assemble, low in cost and good in stability; hardware control is adopted, so that the test accuracy is high, the reliability is good, and the load holding time is long; radial deformation of a test piece can be visually observed, and in combination of shooting equipment and image processing system software, the radial deformation of the test piece can be measured more accurately.

Description

technical field [0001] The invention relates to a visual triaxial test system, which is used for the test of rock (soil) mechanical characteristics. Background technique [0002] The triaxial testing machine is a new type of testing equipment that conforms to the research field of modern rock and soil mechanics and studies the mechanical properties of rock (soil). Confining pressure system, rock extensometer, high and low temperature system, pore water pressure system, rock direct shear test system, and rock shearing and splitting fixtures can be configured according to different requirements. It can automatically complete triaxial compression tests of rocks under different confining pressures, pore permeability tests, high and low temperature environmental tests, etc., and can perform triaxial control in multiple control modes such as unidirectional low cycle cycle and combined waveform program control set by the user. test. Rock triaxial test is an important means to stu...
