摘　　要：喷锚支护是指以喷射混凝土、锚杆为主要支护手段,并通过对围岩的监控量测指导设计与施工,使围岩成为支护体系的一部分,从而合理地利用围岩的地承能力,以保证围岩稳定的隧道修建方法.隧道及地下工程建设中采用喷锚支护进行设计和施工,由传统的整体式衬砌设计中的定值参数法改变为以新奥法原理为基础的动态信息设计方法,不论在设计还是在施工方法及工艺、机具等方面均有很大差异.结合郴州市樟树岭隧道对如何在不良地质条件隧道的施工中应用喷锚支护技术作了进一步阐述.To spray anchor supporting protection is to spray the cement concrete and fix the anchor rod as supporting protection, by means of monitoring and surveying of the surface protection design and construction making the cement concrete becomes part of supporting protection system. It is to apply reasonably load capacity of the protection concrete. The design and construction of tunnel and underground engineering project on the basis of application of spraying supporting from the traditional method of whole project engineering construction supported, the fix parameter changes the new principle of dynamic information design method which is quite difference between the design, construction and design and art and the implements. Taking the Zhang Xu-ling tunnel in Chenzhou as example, this paper describes further the spray technique of supporting anchor application.
