摘　　要：在21世纪隧道施工技术占隧道和地下空间大发展的极大比重,隧道及地下工程具有节能、节约土地资源、环保、抗震防灾等优势,因而在铁路、公路、水利水电、能源、物流、国防等各方面都得以广泛采用。自60多年前,新奥法开始在中国高速铁路隧道施工中应用以来,它以岩体力学理论和隧洞工程建设为依据,充分考虑岩体承受能力,并采取“新奥法”实施手段,即“管超前、严注浆、短开凿、强支撑、早封堵、勤量测”,有效地减小了对岩体的扰动,在隧道施工中得到了广泛的应用。In the 21st century,tunnel construction technology accounts for a large proportion of the development of tunnel and underground space.Tunnel and underground engineering have the advantages of energy saving,land resource saving,environmental protection,earthquake resistance and disaster prevention,so they are widely used in railway,highway,water conservancy and hydropower,energy,logistics,national defense and other aspects.Since the application of NATM in the construction of high-speed railway tunnels in China more than 60 years ago,based on the theory of rock mechanics and tunnel engineering construction,it has fully considered the bearing capacity of rock mass,and adopted the implementation means of“NATM”,namely“pipe overtaking,strict grouting,short excavation,strong support,early plugging,frequent measurement”,which effectively reduces the disturbance of rock mass and has been widely used in tunnel construction.
