摘要:
拉林铁路藏噶隧道洞身穿越蚀变花岗岩地层,受花岗岩蚀变和构造残余应力影响,在施工过程中,围岩变形量大、变形速率快、持续时间长。文章根据现场变形数据、应力测试结果分析,采用优化隧道结构断面形式、长短锚杆结合、稳定掌子面、强化支护结构等综合措施,有效抑制了围岩大变形,保障了现场施工安全,探索总结出了高地应力条件下花岗岩蚀变带隧道大变形的施工控制方法及安全保障措施。
Abstract:
The tunnel barrel of the Zangga Tunnel of Lhasa-Nyingchi Railway passes through the altered granite stratum. Affected by the alteration of granite and the residual stress of the structure, the surrounding rock has large deformation with a fast deformation
