本文研究了泥岩隧道应用新奥法施工的问题,提出施工、治水方案和施工程序，认为加强 围岩量测监控、掌握围岩变形情况用以指导施工是关键。

The paper discusses the problems concerned with the construction of mudstone tunnels by applying NATM. The schemes of construction and water treatment and the engineering pro?cedures are suggested. It is recognized that the key points for guiding the engineering works are： strengthening the supervision of the measurement of the surrounding rocks and controlling the straining manner of the surrounding rocks.
