  • STEREOSCOPIC IDENTIFICATION METHOD AND APPARATUS FOR DISTURBANCE STRESS EVOLUTION PROCESS OF UNDERGROUND CAVE SURROUNDING ROCK
    Publication number: 20230324574
    Abstract: A stereoscopic identification method and apparatus for disturbance stress evolution process of underground cave surrounding rock perform a numerical inverse analysis of three-dimensional stereoscopic disturbance stress of a surrounding rock of the target underground cave on the basis of measurement values of three-component microseismometers and disturbance stress gauges. During the analysis, the overall prediction values are corrected from point to volume based on the measurement values to achieve a high-precision identification effect of the evolution process of the stereoscopic disturbance stress of the surrounding rock.
