针对浏阳河隧道开挖设计的铣挖法,在武广客运专线XXTJⅡ开展铣挖法工艺试验，对铣挖法工艺与设备进行简介，对不同地质条件下的隧道铣挖工艺的效率和成本进行统计分析，得出铣挖法适用范围，为浏阳河隧道以及待建或已建的同类型隧道开挖施工提供借鉴。

Liuyanghe tunnel is designed to be constructed by milling excavation method, therefore milling excavation trials are made in some tunnels in XXTJ Ⅱ bid section of Wuhan～Guangzhou passengerdedicated railway. In the paper, the milling excavation technology and equipment are presented, the efficiency and cost of the milling excavation of tunnels under different geological conditions are summarized and analyzed and the application scope of the milling excavation method is established. The paper can provide reference for the excavation of Liuyanghe tunnel and other similar tunnels in the future.
