摘要
为适应软岩大变形隧道的支护构造对及时主动性和耐久性的要求,提出并研究“树脂端锚+水泥浆全长锚固”的鸟笼锚索系统。通过介绍鸟笼锚索系统的结构组成及施工工艺,并在软岩隧道中开展现场试验研究,为地下工程新型锚索结构的开发与应用提供参考和借鉴。
In order to meet the requirements of initiative and durability of the supporting structure for large deformation tunnel in soft rock,the cage anchor cable system with“resin end anchor+cement slurry full-length anchor”is proposed and studied in this paper.By introducing the structure composition and construction technology of cage anchor cable system,and conducting field test research in soft rock tunnel,the paper provides reference for the development and application of new anchor cable structure in underground engineering.
