围岩力学性能和TBM掘进参数的相关性研究
Dependence of Surrounding Rock Mechanical Properties and TBM Tunneling Parameters
本研究旨在探究围岩力学性能对全断面硬岩隧道掘进机(TBM)隧道掘进过程中刀盘推进力和刀盘扭矩等关键施工控制参数的影响。首先,基于现场实测数据,分析了围岩等级对TBM施工过程中TBM掘进参数的影响,引入单位破岩功作为量化指标,研究了围岩等级的综合影响。在此基础上,采用离散元构建缩尺三维数值模型,模拟TBM刀盘破岩过程,系统分析不同工况下刀盘响应参数的演化规律。研究结果表明:1)岩石的单轴饱和抗压强度由5 MPa提高到75 MPa,刀盘的平均推进力增加了约9.69 kN,刀盘的平均扭矩增加了约1.13 kN·m,单位破岩功增加了约8.22 MJ/m3;2)当刀盘转速从1 r/min提高到5 r/min时,刀盘的平均推进力减少了约5.60 kN,刀盘的平均扭矩减少了约1.41 kN·m,单位破岩功减少了约4.74 MJ/m3;3)当推进速度从10 mm/min提高到50 mm/min时,刀盘的平均推进力增加了约9.33 kN,刀盘的平均扭矩增加了约2.05 kN·m,单位破岩功增加了约7.92 MJ/m3。研究结果揭示了岩石单轴饱和抗压强度、刀盘转速和推进速度对刀盘受力及单位破岩功的影响规律,可为不同地质条件下TBM掘进参数的优化提供理论依据。
The influence of surrounding rock mechanical properties on key tunneling control parameters, such as thrust force and cutterhead torque, during tunnel boring machine (TBM) operations was investigated.Based on field data, the impact of rock mass rating on TBM performance was analyzed, and the specific energy of rock breaking was introduced as a comprehensive evaluation indicator. A scaled 3D discrete element model was developed to simulate the rock fragmentation process by the TBM cutterhead, systematically examining the evolution of cutterhead response parameters under various working conditions.The results show that: 1) Increasing the uniaxial saturated compressive strength of rock from 5 MPa to 75 MPa led to increases in average cutterhead thrust, torque, and specific energy by approximately 9.69 kN, 1.13 kN·m, and 8.22 MJ/m3, respectively; 2) Raising the cutterhead rotation speed from 1 r/min to 5 r/min resulted in reductions of about 5.60 kN in thrust, 1.41 kN·m in torque, and 4.74 MJ/m3 in specific energy; 3) Increasing the advance rate from 10 mm/min to 50 mm/min caused increases of approximately 9.33 kN in thrust, 2.05 kN·m in torque, and 7.92 MJ/m³ in specific energy.These findings clarify the effects of rock strength, cutterhead speed, and advance rate on cutterhead load and rock-breaking efficiency, providing a theoretical basis for optimizing TBM operational parameters under varied geological conditions.
