摘要
本文通过天生桥二级(坝索)水电站3条引水隧洞开挖发生的岩爆现象,总结出岩爆发生的规律(即岩爆现象,岩爆爆裂面的形态特点、类型,破裂面的力学特性,岩爆的深度和宽度,岩爆发生时间及岩爆沿洞轴线分布规律等)及预测岩爆的方法。
Through the rock burst phenomena occurring during the excavation of 3 diversion tunnels of Tianshengqiao Ⅱ (Basuo) Hydropower Station, this paper presents the law of rock burst (i. e. depth and width of rock burst, time of occurrence and its distribution along the axis of tunnel) and its prediction method.
