摘要
隧道系统锚杆的设计大多采用工程类比法,没有充分考虑到围岩对支护结构的影响.隧道围岩和支护结构作为一个统一的整体,二者共同组成"围岩-支护"体系参与作用,并通过承压拱机理,对隧道系统锚杆的设计计算理论进行研究,从而确定其合理参数,降低建设成本。
Most of tunnel system bolt design are analogical between each other without any consideration of the effect of surrounding rock. Taking tunnel surrounding rock and supporting as an unifier, a surrounding rock-support system was built up to join in work. Through bearing-load arch theory, and calculation theory study of tunnel system bolt, the certain parameters were ascertained to reduce the cost of construction.
