摘要
针对贵州省都安高速公路T31标段地质、水文等客观条件,对其公路隧道的钻爆方案进行了设计,包括不同围岩级别的炮眼布置、爆破参数和起爆顺序的设计,此外还给出了隧道的施工原则和方案,包括爆破开挖施工工艺流程图和新奥法施工工艺流程图,研究成果对类似的工程项目具有重要的参考价值和意义。
Based on the objective conditions of geology and hydrology of T31 section of Duan Expressway in Guizhou Province,this paper designs the drilling and blasting schemes of highway tunnels,including the design of blastholes,blasting parameters and detonation sequence of different surrounding rock grades.The construction principles and schemes of the tunnel,including the blasting excavation construction process flow chart and the new Austrian construction process flow chart,the research results have important reference value and significance for similar engineering projects.
