摘要
以十堰—天水联络线磨河村隧道工程为例,简要介绍了千枚岩隧道中出现地下水及产生变形的机理,针对隧道支护体系中常用系统锚杆的优缺点进行了分析,通过施工验证,指出隧道支护体系的核心是利用围岩自身应力达到稳定。
Taking the contact line of Shiyan -Tianshui Moheeun tunnel project as an example, it briefly introduces ground water appearance and deformation mechanism in the phyllite tunnel. It analyzes advantages and disadvantages of systematical bolts commonly used in tunnel support system. Through the construction verification, it points out that the core of the tunnel support system is the use of self-stress of surrounding rock to achieve stability.
