摘要:
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。
Abstract:
In order to solve the technical problem of large deformation of tunnel in the high ground stress and strongly weathered carbonaceous slate stratum,taking the large deformation treatment of a tunnel in the strongly weathered carbonaceous slate stratum as the research background,the large deformation control technology of resistance-limiting and energy-dissipating was studied by using the indoor test and numerical simulation method.The results show that the bearing capacity and energy absorption effect of resistance-limiting and energy-dissipating device with the structure type of counter-prefolding corrugated pipe are better than the devices with other structure types.After installing the resistance-limiting and energy-dissipating device with counter-prefolding corrugated pipe on the steel frame,the deformation of steel frame reduce，the overall stress of tunnel lining structure decreases,and the safety coefficient increases.The minimum safety coefficient of the monitoring section increases by 15.79%,which means that the resistance-limiting and energy-dissipating device with counter-prefolding corrugated pipe can be used as the circumferential treatment measure for the large deformation of tunnel in the high ground stress and strongly weathered carbonaceous slate stratum.The results can provide reference for the large deformation treatment design of similar engineerings.
