自稳隐形拱理论在岩质隧道锚杆支护工程中的应用探讨

摘要

This article presents the theory of invisible arch bolting,which is simulated and analyzed by use of the FLAC-3D software.Bolting design ideas are identified tentatively for tunnel construction.Data indicates that this method can effectively control the deformation of tunnel surrounding rock,and provide a new basis for rock tunnel support.%阐述了自稳隐形拱锚杆支护理论,利用FLA C-3D软件对该理论进行了模拟和分析,并初步研究和确定了适合隧道施工的锚杆支护设计思路.现场施工监测表明,该方法可以有效控制隧道围岩的变形,为岩质隧道支护设计提供了新的依据.
