By means of experimental method of dynamic caustics,the dynamic fracture behaviors,such as,stress intensity factor,extension track,and crack's extending velocity and acceleration of precast beams with a single crack and double cracks under impact loads were analyzed comparatively. The experiment results indicated that when the impact point is directly upon the main crack,the double-crack beam's cracking initiation time is the earliest with a extension track of the main crack slightly offsetting to the secondary crack in the late stage of cracking extension; the single-crack beam of I-type's cracking initiation time is secondary with a straight line extension track of the main crack; the cracking initiation time of the double-crack beam with two cracks offset to the impact point is the latest with obvious bending fracture; the more serious the bending fracture phenomenon during the process of crack extension,the smaller the maximum extending velocity; in the whole process from the hammer contacting the beams to specimens fracture,their stress intensity factors vary oscillatorily; the stress intensity factors of the secondary crack of the double-crack beam decrease dramatically in the middle stage of the main crack extending.
