| 摘 要： | 为评估某深竖井目前施工段围岩岩爆烈度等级，基于AHP-FUZZY理论方法并结合现场施工实际，综合考虑现有理论判据和岩爆发生机理，选取脆性系数、弹性能指数等8个评价指标预测岩爆等级，结果表明其竖井围岩无岩爆倾向性。同时结合损伤理论从岩体强度、储能能力、劣化程度等方面解释了其倾向性，其结果可为竖井现场施工和支护设计提供参考价值。

| Abstract: | In order to evaluate the rock burst intensity level of surrounding rock of a deep shaft at present construction stage, based on AHP-FUZZY theory method and combined with field construction practice, considering the existing theoretical criterion and rock burst mechanism, eight evaluation indexes such as brittleness coefficient and elastic energy index were selected to predict rock burst intensity level. The results show that there is no rockburst tendency in the surrounding rock of the shaft. At the same time, combined with rock damage theory, its tendency is explained from the aspects of rock strength, energy storage capacity and degradation degree. The results can provide reference value for site construction and support design of shaft. |
