Abstract

The invention relates to a microcosmic crack, acoustics and mechanics synchronous detection system for a rock. The microcosmic crack, acoustics and mechanics synchronous detection system comprises a testing machine, and further comprises a mechanical system, an ultrasonic system, an infrasound system, a crack detection system and a PC machine system, wherein the mechanical system transmits stress and strain data, which are generated in a rock destroying process on the testing machine, to the PC machine system; the ultrasonic system transmits an ultrasonic signal, which is generated in the rock destroying process, into the PC machine system; the infrasound system acquires infrasound data generated in the rock destroying process and transmits the infrasound data to the PC machine system; the crack detection system transmits a crack evolution process of a rock observation surface into the PC machine system. The microcosmic crack, acoustics and mechanics synchronous detection system for the rock can synchronously detect the mechanics, microcosmic cracks and ultrasonic wave and infrasound activity rules in the rock destroying process, so as to commonly describe the deforming and destroying mechanism of the rock and pre-warn the overall instability of the rock (mass).

Description

technical field [0001] The invention belongs to the technical field of rock failure tests, and in particular relates to a simultaneous detection system for rock mesoscopic cracks and acoustic mechanics. Background technique [0002] The mechanism of rock deformation and failure and the prediction of rock instability have always been the hotspots of research, and many scholars have done a lot of work by using different means. To sum up, there are generally the following aspects: The first aspect is the monitoring of the crack evolution process in the rock failure process. The law of crack evolution; Ge Xiurun et al. described the shape and propagation mechanism of cracks in the process of rock failure by using CT scanning method; The developed image analysis combined with digital image correlation technology conducted experimental research on the deformation and failure characteristics of prefabricated single-cracked rocks under uniaxial compression; Zhu Zhende extracted the...
