【摘要】 分析总结西南某电站辅助隧洞的岩爆发育特征,然后用扫描电镜技术(SEM)对岩爆岩石断口进行微观断裂形貌研究,并总结其破坏力学机制,最终建立起岩爆岩石的微观断裂方式和破坏力学机制与宏观岩爆特征及其烈度的关系。更多还原

【Abstract】 This paper firstly summarize the development character of the rock burst in the subsidiary tunnel of a hydroelectric power station in southwest, and then analyse the microcosmic figure of the rock’s rupture surface with the technique of SEM and bring forward the mechanism mode of microcosmic failure. At last, build the relationship between the rock microcosmic rupture mode, failure mechanism and the macroscopical character of the rock burst and its intensity.更多还原
