Abstract

The present application provides a quantitative assessment method, apparatus and device for global stability of surrounding rocks of underground caverns, which are configured to provide a concrete, practical and effective quantitative assessment solution for a global stability state of the surrounding rocks of the underground caverns. The quantitative assessment method for global stability of surrounding rocks of underground caverns includes: extracting, after determining an assessment task for the global stability of the surrounding rock of a target underground cavern, initial data of the target underground cavern; dividing, according to the initial data, the target underground cavern into different independent cavern units or cavern sections; and rating, according to a preset stability assessment strategy, the eight factors influencing the stability of surrounding rocks of cavern units or the cavern sections are rated respectively, as a global stability assessment result of the target underground cavern.
