摘　　要：锚杆喷射混凝土支护是隧洞塌方临时支护的主要措施。就锚杆喷射混凝土支护技术,在泄洪隧洞工程软弱夹层塌方段的支护措施进行阐述,主要从锚杆施工、原材料的控制、施工机具、混合料的配合与拌制,喷射前的准备工作、喷射作业、安全技术,施工要点等几方面进行论述,供同类隧洞工程施工时参考和借鉴。The supporting technique with the anchor and sprayed concrete is a main measure for supporting temporarily when the tunnel collapsed. Here, the applied conditions of this technique in the soft interlayer collapse section of a flooddischarging tunnel are discussed, such as the anchor construction, control of raw materials, construction machines and tools, mixing of composite materials, preparation before spraying, spraying operation, safely and construction points, etc. These experiences could provide the references for the similar projects.
