摘　　要：对于川藏铁路隧道工程采用钻爆法施工机械的选型,分析了近二十年来高原寒区铁路长大隧道无轨运输施工机械配置情况,针对川藏铁路隧道不良地质和现有的应对措施,介绍与之相适应的机械设备,并对有利于隧道钻爆法机械化施工的开挖方法提出建议。For Sichuan-Tibet railway tunnel project,the configuration of the trackless transport construction machinery of the railway long tunnel in frigid highland zone in recent twenty years was analyzed through the type selection of the construction machinery using drilling and blasting method.The corresponding mechanical equipment was introduced based on the unfavorable geology of the Sichuan-Tibet railway tunnel and the existing countermeasures and suggestions for the excavation method to the benefit of the mechanized construction using tunnel drilling and blasting method were proposed.
