摘要
为了对比研究TBM刀盘滚刀破岩过程中贯入力特性,系统的总结了几个典型的滚刀破岩贯入力与贯入度关系预测模型。以某地下引水工程隧道变质花岗岩作为工程背景,以普遍采用的19英寸滚刀作为算例,分析了盘形滚刀法向力和滚动力与贯入度关系之间的关系。研究表明,滚刀法向力和滚动力近似与贯入深度近似成正比。滚刀滚动力比法向力小了近似一个数量级。
In order to compare and investigate the penetration force characteristics in the process of rock breaking with TBM cutter hob, several typical prediction models of the relationship between the penetration force and penetration degree of rock breaking with hob were systematically summarized. Taking the underground tunnel with metamorphic granite as engineering background, and widely used disc cutter with diameter of 19 inch as simulation example, the relationship models between penetration forces and penetration depth during cutting rock for disc cutter are analyzed. The computing results show that the normal force and rotating force are in proportion to penetration depth. The normal force is 10 times as hob rotating force.
