摘　　要：新奥法施工工艺作为一种重要的隧洞开挖方式被广泛应用于各类隧洞施工中,在施工过程中要根据工程建设的具体情况和隧洞所处区域的地质条件不断调整和完善施工工艺,以确保施工工艺满足设计施工要求。对天水市城区引洮供水工程中新奥法施工工艺的应用进行了分析,该工程利用新奥法施工工艺有效完成了隧洞开挖支护工作,同时也为新奥法工艺的具体实践提供了新的案例。As an important tunnel excavation method,New Austrian Tunnelling Method(NATM)is widely used in various tunnel construction.During the construction process,the construction technology should be adjusted and improved continuously according to the specific conditions of the project construction and the geological conditions of the tunnel area to ensure that the construction technology meets the design and construction requirements.This paper analyses the application of NATM construction process in Yintao Water Diversion Project in Tianshui city.The project effectively completes the support work for tunnel excavation by using NATM,and also provides a new case for the specific practice of NATM.
