The invention discloses an explosion loading electric measurement-dynamic photoelasticity hybrid experiment system and method. The system comprises a laser light source (1), a beam expanding mirror (2), a convex lens A (3), a polaroid A (4), a quarter-wave plate A (5), a quarter-wave plate B (6), a polaroid B (7), a convex lens B (8), a high-speed camera (9), a computer (10), an experiment loadingplatform(11), a delay and controller (12), a multi-channel pulse igniter (13), a super-dynamic strain gauge (14), a data acquisition instrument (15), a test piece (33), explosive cartridges(34), a bridge box, a signal line, a shield line and a strain gauge. The system combines the advantages of two experiment methods, can measure various mechanical parameters, such as moving crack spreading speed, crack tip region strain, dynamic stress intensity factor and dynamic fracture toughness, and can also obtain information of test piece total stress field dynamic photoelastic fringes and focal speckle series images and the like; and by comprehensively comparing and analyzing the data obtained by the two methods simultaneously, a propagation mechanism of explosion-induced moving cracks and interaction of the moving cracks during the propagation process can be studied more accurately, scientifically and quantitatively.
