摘要
西秦岭特长隧道围岩地质构造复杂,断层较为发育,且处于高地应力区域。文章通过揭示F54断层施工,重点介绍了该断层地质特征及应力变化规律,阐述了施工方法及支护参数,为下一步开挖其它断层施工总结经验,提供借鉴。
The geological structure of surrounding rocks of super-long West Qinling tunnel is complex and the tunnel is located in the area of high ground stresses with developed faults.The paper introduces the geological characteristics and regulations of stress variation of the fault based on the tunnel driving through F54 fault,describes the construction method and support parameters of the project.
