摘要
为掌握TBM掘进参数与地质参数、操作参数、刀盘刀具设计参数的相关性,基于滚刀受力CSM模型,通过近似计算与推导,建立了滚刀破岩力与结构参数、TBM操作参数、地层强度参数σc的定量关系模型。同时,通过室内缩尺滚刀试验,对推导的模型参数关系进行验证。针对TBM掘进参数与围岩条件的匹配性关系,以大瑞铁路高黎贡山隧道TBM施工为依托,通过数据统计分析与对比,提出使用转矩与推力的比值作为判断地层完整性发生变化的依据。
In order to grasp the correlation between TBM tunneling parameters and geological parameters, operation parameters and cutterhead design parameters, based on CSM model of hob force, the quantitative relationship between rock breaking force and structure parameters of hob, TBM operation parameters and formation strength parameters is established by approximate calculation and derivation.The relationship of parameters derivated is validated by indoor scale hob test.For the matching relationship between TBM tunneling parameters and surrounding rock conditions, based on the TBM in Gaoligongshan Tunnel of Dili-Ruili Railway, the method, using the ratio of thrust and torque to judge the change of formation integrity is put forward after data analysis and comparison.
