摘要:
全断面隧道掘进机TBM掘进过程中刀盘上的盘型滚刀存在协同破岩过程。为了研究滚刀协同破岩对TBM破岩效率的影响,采用有限元数值模拟方法,分析了三滚刀线性切割协同破岩和回转切割协同破岩对TBM破岩效率的影响。根据临空面数量将三滚刀协同破岩划分为同次破岩、顺次破岩、由内向外破岩、由外向内破岩4种模式,结果表明:有两个临空面的由外向内破岩的破岩滚动力、法向力以及比能的整体趋势均最小,即4种破岩模式中由外向内破岩效率最高;当刀间距与贯入度的比值为30时,滚刀破岩比能最小,破岩效率最高;滚刀线性切割试验数据向回转切割试验数据转化时,滚动力和比能的换算系数均为1.35,法向力的换算系数为0.87。该结论为TBM运行过程中操作参数的设置以及刀盘的设计提供了理论依据。
Abstract:
During the excavating operation of a tunnel boring machine (TBM), the disc cutters on the cutterhead work together to break up rock. To investigate the influence of cutter breaking on TBM breaking efficiency, in this study a finite element numerical simulation approach was employed to compare the effects of three cutters linear cutting breaking and rotary cutting breaking.According to the number of crucial surfaces, the three cutters breaking was classifed into, sequential breaking, inward-outward breaking, and outward-inward breaking. The results showed that outward-inward rock breaking with two critical surfaces had the least overall trend of rolling force, normal force, and specific energy, indicating that it was the most efficient of the four rock breaking modes. When the blade spacing to penetration ratio was 30, the roller cutter had the lowest specific energy for breaking rocks and the maximum efficiency. When the cutter′s linear cutting test data was converted to rotary cutting test data, the conversion coefficients for rolling force and specific energy were 1.35, while the conversion coefficient for normal force was 0.87. This study casted extra light on a theoretical basis for determining the operating parameters and designing the cutter for the TBM′s operation procedure.
