岩爆作为深埋隧洞开挖后常见的一种地质灾害,严重威胁着施工人员和现场设备的安全。从岩性与应力两个方面入手,结合实际情况和现场试验,采用可拓综合评判对某隧道岩爆等级进行预测。岩性方面的指标采用现场岩石力学试验确定,应力方面的指标采用空芯包体法地应力测量和有限元数值模拟计算确定,通过对比分析和现场实际验证,该评价结果合理,对后期施工起到了很好的指导作用。 Rockburst, as a common geological disaster after excavation of deep tunnel, threatens the safety of construction workers and on-site equipment seriously. Starting from two aspects of lithology and stress, combined with the actual situation and field test, the comprehensive evaluation of extension can be used to predict the rock burst level of a tunnel. The lithology indexes are determined by the on-site rock mechanics test. The stress indexes are determined by the stress measurement of the hollow core inclusion method and the finite element numerical simulation. By comparative analysis and actual field verification, the evaluation results are reasonable. To a good guide.
