摘要:
为探究盘形滚刀形式对TBM 破岩效率的影响,依托福州滨海快线工程项目,利用ABAQUS 创建盘形滚刀破岩模型,通过优化单刃滚刀结构参数,分析多滚刀破岩方式对掘进效率的影响。结果表明:刃宽和贯入度对滚刀破岩的影响最大,随着刃宽和贯入度增加,滚刀受到的滚动力、垂直力和破岩体积逐渐增大,并在刃宽20 mm、贯入度10 mm 时,达到最佳破岩效果;双滚刀下采用同步破岩的效率要明显高于顺次破岩,其最优刀间距为60 mm;随着四滚刀回转半径增加,滚刀受到的切向力、垂直力和合力均增大,侧向力呈现先增大后减小的趋势,在回转半径350 mm 处达到最大。研究成果可为福州滨海快线项目TBM 滚刀选型及施工方案优化设计提供依据。
Abstract:
To investigate the impact of disc cutter geometry on TBM rock-breaking efficiency, based on the geological parameters of the Fuzhou Coastal Express Line project, a disc cutter rock-breaking model was created using ABAQUS. By optimizing the structural parameters of a single cutter, the effects of multiple-cutter rock-breaking methods on tunneling efficiency were analyzed. Results show that cutting width and penetration depth have the greatest impact on rock-breaking; with the increase in cutting width and penetration depth, the rolling force, vertical force and rock volume gradually increase, reaching the best rock-breaking effect when the cutting width is 20mm and penetration depth is 10mm. The efficiency of synchronous rock breaking with double disc cutters is significantly higher than that of sequential rock breaking, and the optimal cutter spacing is 60 mm. With the increase of the rotation radius of the four-disc cutter, the tangential force, vertical force and combined force acting on the hob increase. The lateral force presents an increasing trend before decreasing and reaches its maximum value at the circumference of 350mm. The research results can provide a basis for the selection of TBM cutters and the optimization design of construction schemes for the Fuzhou Coastal Express Line project.
