为进行岩石耐磨性与矿物硬度之间的关系研究,文章通过建立岩石加权莫氏硬度数学模型的方法对岩石硬度进行描述,再用数理统计方法,对采集的隧道岩石耐磨性与岩石加权莫氏硬度进行相关性研究。通过建立数学关系模型分析得出加权莫氏硬度与岩石耐磨性具有较大相关性,其可以作为TBM施工重要的技术参数。 In order to study the relationship between the wear resistance of rock and mineral hardness, the paper describes the rock hardness by establishing the mathematical model of rock-weighted Mohs hardness and then uses the mathematical statistics method to calculate the wear resistance and rock weight of the collected tunnel rock Mohs hardness correlation study. Through the establishment of the mathematical relationship model, it is concluded that the weighted Mohs hardness has a great correlation with the wear resistance of rock, which can be used as an important technical parameter of TBM construction.
