摘要
预测滚刀寿命,根据刀具磨损规律把握最好的换刀时机对隧道掘进机(TBM)来说是极其重要的。文章以秦岭隧道为例,应用围岩分类来预测刀具消耗量。根据影响TBM掘进率的岩石单轴抗压强度、岩石耐磨性、岩石硬度及岩体节理发育程度对围岩TBM工作条件等级的划分,定性分析了围岩等级与刀具消耗量的关系。在此基础上,提出围岩等级数的概念,得出不同的等级数与其相应的耗刀量之间的定量关系。
It is very important to change the cutter at the right time for TBM according to the cutter life prediction. Using the rock mass classification to predict the cutter life is presented in this paper, referring to the case for medium to hard rock of the Qinling tunnel. The cutter consumption in different rock mass is qualitatively analyzed. The quantitative relation between rock mass grading and the consumption of cutter used is proposed.
