强风化炭质板岩地层隧道限阻耗能大变形控制技术研究
Journal of Safety Science and Technology（2023）
Abstract
为解决高地应力强风化炭质板岩地层隧道大变形技术难题,以某强风化炭质板岩地层隧道大变形处治为研究背景,采用室内试验及数值仿真方法对限阻耗能大变形控制技术进行研究.研究结果表明:反预折纹管结构型式限阻耗能装置承载力与吸能效果均优于其他结构型式装置;将反预折纹管限阻耗能装置施设于钢架后,钢架变形有所减小,隧道衬砌结构整体应力有所降低,安全系数有所增加,监测断面最小安全系数增加 15.79%,表明反预折纹管限阻耗能装置可作为高地应力强风化炭质板岩地层隧道大变形环向处治措施.研究结果可为类似工程大变形处治设计提供参考.
