摘要
文中通过收集大理下河坝-双廊一带的二叠系峨眉山组玄武岩的勘察资料,分析了该区域玄武岩的喷发规律与岩石构造特征,以及岩性、风化、岩体结构、物理力学参数等工程特性,分析了该区域隧洞工程围岩破坏模式与机理,为该区域工程研究玄武岩提供借鉴。
By collecting the survey data of the basalt of Permian Emishan Formation in Xiheba-Shuangliang area of Dali,this paper analyzes the erupting rule and rock structure characteristics,as well as the engineering characteristics of lithology,weathering,rock structure and physical and mechanical parameters of the basalt in this area,and analyzes the failure mode and mechanism of surrounding rock of the tunnel engineering in this area,which provides reference for the research of basalt in this area.
