Abstract: Based on the Hejiazhuang tunnel on the Zhengzhou-Xi’an passenger dedicated railway, forcing cases of systematic anchor was studied in loess tunnel with large cross-section and forcing characteristics of systematic anchor at vault and sidewall parts were obtained; reasons why the forcing difference varies much were analyzed from the perspective of the law of radial displacement attenuation and distribution form of surrounding rock pressure; the related conclusions will offer reference value and guiding significance to the design and construction of such tunnels.

Key words: loess tunnel with large cross-section, systematic anchor, radial displacement attenuation, distribution of surrounding rock pressure

摘要: 以郑西铁路客运专线上的贺家庄隧道为例,研究了大断面黄土隧道中系统锚杆的受力状况,得出了拱部和边 墙锚杆的受力特点,从径向位移的衰减规律和围岩压力分布形式两个角度分析了系统锚杆受力差异较大的原因,相 关研究结论对黄土隧道的设计和施工具有参考价值和指导意义。

关键词: 大断面黄土隧道, 系统锚杆, 径向位移衰减, 围岩压力分布
