摘　　要：近十几年来我国的高速铁路发展速度有目共睹,对高铁施工技术要求逐步提高,各种铁路建设技术攻克要迎难而上,敢为人先、科技创新。文章结合高速铁路阳春隧道工程施工实例,简要叙述了采用新奥法原理的隧道开挖技术、仰拱初支成环施工技术的研究,给出了施工工艺以及技术措施、初支安全措施、环水保风险与预防、结束语事项,为高速铁路隧道工程施工技术提供了重要参考和借鉴。In the past ten years,the development speed of China's high-speed railways is obvious to all.The technical requirements for high-speed railway construction are gradually increasing.Various railway construction technologies must overcome difficulties,dare to be the first and innovate in science and technology.Based on the construction example of the Yangchun tunnel of the high-speed railway,the article briefly describes the study of the tunnel excavation technology and the construction technology of the inverted arch initial support and ring formation using the new Austrian method principle.The construction technology and technical measures,the initial support safety measures,the ring Soil and water conservation risks and prevention,concluding remarks,provide important reference and reference for the construction technology of high-speed railway tunnel engineering.
