The present invention discloses a true triaxial test ultrasonic wave and acoustic emission testing system. According to the present invention, a true triaxial test apparatus has six sides of pressurization units, wherein ultrasonic wave and acoustic emission coupling test transducers are arranged between every side of the pressurization unit and corresponding surfaces of rock, a communication terminal of at least one ultrasonic wave and acoustic emission coupling test transducer is connected with a signal output terminal of a multi-channel ultrasonic wave defect detector, communication terminals of other ultrasonic wave and acoustic emission coupling test transducers are respectively connected with a signal input terminal of the multi-channel ultrasonic wave defect detector and a signal receiving terminal of an acoustic emission instrument through signal shunts, and the acoustic emission instrument and the multi-channel ultrasonic wave defect detector are connected with a computer. With the present invention,
