摘要
天生桥二级水电站引水发电隧洞,85%的洞段分布坚硬的石灰岩和白云岩,开挖过程中发生了频繁的岩爆。进行岩爆的烈度分级,是一项重要的有意义的工作。本文将岩爆分为4级,除特强岩爆之外,强烈、中等及弱岩爆。
Hard limestone and dolomite cover 85%of length of the power tunnels of Tianshengqiao (Ⅱ) Hydropower Project During excavation,rockburst occurred frequently It is of significance to classify the intensity of rockburst This paper proposes 4 classes for the tunnels Except for very strong intensity,there have been of occurrence rockbursts of strong,medium and weak intensities
