岩爆特征及岩体结构效应 总被引：15，自引：0，他引：15
本文论述了中国南盘江天生桥大型水电站引水隧洞中的岩爆特征及岩爆岩体结构效应。指出岩体结构对岩爆的发生和岩爆烈度具有控制作用,并结合岩爆岩石力学试验,提出了岩爆岩体结构效应理论。对于正确选择地下工程场地、调整优化洞室轴线方位和岩爆预报具有实用价值。 相似文献

This paper is concerned with the rockbursting characteristics and the structural effectsof the rock masses in the diversion tunnel of Tianshengqiao Hydropower Station. The control-ling effect of rock mass structure on the occurrence and intensity of the rockburst is demon-strated. At the same time the theory of rock mass structural effect on rockbursting has beenadvanced with rock mechanical tests carried out by the author. It laid the foundation of thecorrect selection of the underground project sites where occurs no rockburst, and it also laidthe foundation of adjusting the tunnel axes to reduce the rockburst intensity and predictingthe rockburst under the construction of underground projects. 相似文献
