Stress-water flow-ohemical coupled rock urpture process mesomechanic loading system

The present invention discloses a stress - water - chemical coupling of rock failure MICROMECHANICAL loading system. The system consists of a servo control system (1,2,3), U-type rigid loading platform (4), the movable support (5), a movable holder (6), three-dimensional video microscopy digital recording system (8), two monitors device (9, 11), the video distributor (10), two digital cameras (12, 13) and two CCD cameras (14, 15) composition. The servo control system will be placed on a rigid U-shaped loading platform (4), suitable for placing the stress - water - micromechanics chemical coupling uniaxial testing apparatus and chemically etching the rock fracture mechanics test means the whole process of triaxial compression meso , the stress can be - water - chemical corrosion cOUPLED rock fracture mechanics test meso, chemical corrosion and different confining pressures of rock fracture micromechanics experiment, the crack and the whole process of the specimen extended microscopic observation CCD amplifies ,recording.
