机械设备是铁路基本建设的重要手段,是重要的物资技术基础。建国以来,由于我国铁路施工机械及机械化施工的迅猛发展,有力地促进了技术进步和工艺改革,大大加快了建设速度,相继出现了一系列以机械化施工为主要方式的大型工程。1981年开工的大瑶山双线铁路隧道,就是铁路隧道施工典型的一例。该隧道虽然地质结构复杂,工程
Mechanical equipment is an important means of railway infrastructure, is an important material technology base. Since the founding of the People’s Republic of China, due to the rapid development of China’s railway construction machinery and mechanized construction, the technical progress and technological reform have been vigorously promoted, the construction speed has been greatly accelerated, and a series of large-scale projects with mechanized construction as their main mode have emerged one after another. The Dayaoshan double-track railway tunnel started in 1981 is a typical case of railway tunnel construction. Although the tunnel complex geological structure, engineering
