The process of building rock failure is often accompanied by stress drop and energy release, which seriously threaten the safety of building structures. To reveal the law of energy release and transformation in the process of rock stress drop and establish a rock structural health monitoring index based on stress drop energy, the relationship between the stress drop and acoustic-electrical (acoustic emission and electromagnetic radiation) energy of the shale and limestone failure process is studied in this paper. The results show that, in the early stage of rock loading, there is almost no stress drop dissipated energy, and the change in acoustic-electric signals is not obvious. In contrast, in the later stage of deformation and failure of rock, the generation process of stress drop is accompanied by significant stress drop dissipated energy and acoustic-electric energy release. With the increase in stress drop dissipated energy, the released acoustic-electric energy gradually increases, and there is a good linear positive correlation. The release mechanism of the acoustic-electric energy in the process of stress drop is mainly related to the crack propagation effect. The more significant the stress drop is, the faster the crack unstable propagation, the more intense the charging and discharging processes are on the crack faces, and the more acoustic-electrical energy is released. Finally, a new indicator of rock structure health monitoring based on stress drop energy is established by a statistical method, and the health status of the rock mass structure is divided into weak, medium and strong danger, thus reflecting the stress distribution state and structural stability of rock.

基于应力降和声电能量释放的建筑岩石结构健康监测

应力降的产生过程伴随着显着的应力降耗散能和声-电能释放。随着应力降耗散能的增加，释放的声-电能逐渐增加，呈良好的线性正相关。应力下降过程中声-电能的释放机制主要与裂纹扩展效应有关。应力降越明显，裂纹不稳定扩展越快，裂纹面的充放电过程越强烈，释放的声电能越多。最后，通过统计方法建立了一种基于应力降能量的岩体结构健康监测新指标，将岩体结构的健康状态分为弱、
