摘要
本文针对地下洞室工程中预应力锚索加固围岩的优越性设计问题,以全长黏结式锚索加固围岩为例,用有限元软件FLAC3D对其进行了建模,开展了加锚抗剪切性能的模拟研究和理论探讨,对比了两种方案下黏结式预应力锚索加固前后的计算结果,阐述了地下洞室工程围岩黏结式预应力锚索支护机制,解释了采用黏结式预应力锚索加固围岩的优越性,可以为工程设计人员提供一定的参考。
In the paper, full length adhesive anchor cable reinforcement surrounding rock is adopted as an example, finite element software FLAC3D is utilized for modeling aiming at superiority design issue of pre-stressed anchor cable reinforcement surrounding rock in underground cavern project. Anchor shear resistance performance simulation study and theoretical discussion are implemented. Calculation results of before and after adhesive pre-stressed anchor cable reinforcement under the two plans are compared. Surrounding rock adhesive pre-stressed anchor cable supporting mechanism of underground cavern project is described. Superiority of adopting adhesive pre-stressed anchor cable reinforcement surrounding rock is explained. The paper can provide certain reference for project designers.
