摘要:
为了研究刀盘出碴槽结构参数对全断面岩石掘进机(TBM)出碴特性的影响规律,本文以某供水隧道工程为背景,考虑掘进过程中岩碴产生、下落以及与滚刀碰撞等因素,建立TBM刀盘(含滚刀)出碴过程数值计算模型,探究出碴槽长宽比、开口角度对刀盘出碴性能的影响规律。仿真结果表明:排碴过程中,岩碴颗粒数量的增长速率先快后慢,最后趋于平稳;TBM刀盘开口面积一定时,随着出碴槽长宽比增大,排碴量加速下降43%;随着出碴槽开口角度的增大,排碴量呈现先增大后减小趋势;当开口角度为35°时,出碴效率最高。设计出碴槽时,在控制开口宽度尽量大的前提下,开口角度优化范围为20°~35°。设计的针对该供水工程的TBM刀盘开口,经过两年多的工程掘进,效果良好。
