摘　　要：白龟山水库尾水隧洞工程灰岩有破碎软弱带,部分夹杂着弱风化易碎钙质页岩,并且部分洞段有喀斯特地貌和地下水,施工难度较大。为此,采用综合开挖支护技术,使隧洞工程顺利竣工。本文详述了隧洞开挖支护的施工程序和方法,可为类似工程施工提供借鉴。Limestone of Baiguishan Reservoir tail water tunnel project has a broken weak belt.It is partially mixed with weak weathering fragile calcareous shale.In addition,a part of caves have karst landform and groundwater,thereby the construction is difficult.Therefore,comprehensive excavation support technology is adopted to achieve smooth completion of tunnel project.Construction procedure and method of tunnel excavation support are described in the paper,which can be used as reference for similar projects.
