摘要: 针对新疆某输水工程所用的多种TBM刀盘,为研究不同刀盘在掘进过程中滚刀磨损差异,从现场2TBM4#5#)滚刀实测磨损数据入手,利用数值归纳方法研究了刮渣斗数量、刮渣斗与紧邻滚刀夹角对滚刀磨损的影响。通过向量分析方法得到以下结论: 1)刮渣斗的布设数量对滚刀磨损的影响较为显著,刮渣斗布设多的滚刀磨损较小,刀盘设计时应多布设刮渣斗。2)滚刀应尽量布设在紧邻前方刮渣斗处。3)相邻刮渣斗之间布设多把滚刀时,应确保外侧滚刀紧邻前方刮渣斗布设。

Abstract: To study the wear difference of disc cutters of various tunnel boring machine (TBM) cutterheads used in a water conveyance project in Xinjiang, the wear data measured from the disc cutters of TBMs #4 and #5 are analyzed, and the effect of factors, including the number of mucking slots and the angle between mucking slot and adjacent disc cutter, are studied using a numerical induction method. The vector analytical results show the following. (1) The number of mucking slots has a significant effect on the disc cutter wear, and the more the mucking slots, the less the disc cutter wears, and more mucking slots should be arranged in the cutterhead design. (2) The disc cutter should be arranged close to the front mucking slot. (3) When multiple disc cutters are arranged between adjacent mucking slots, the lateral disc cutter should be close to the front mucking slot.
