摘　　要：为了研究TBM掘进参数与不同岩性地层的相关性规律,以新疆某引水工程为背景,针对典型岩性地层选取了300 m掘进参数数据,采用数理统计方法分析3项掘进参数与6种岩性地层的相关性.通过分析6种岩性地层下刀盘转速、总推力与推进速度之间相关性,提出6种岩性地层下的掘进建议.结果表明:各种岩性地层中推进速度、总推力的平均值差距较大,且有较大波动;刀盘转速波动不大,平均值差异较小;硅质岩、安山岩和凝灰岩地层下,总推力、刀盘转速和推进速度不相关;糜棱岩和砂岩地层下,总推力、刀盘转速和推进速度正相关;碎裂岩地层下总推力与推进速度负相关.In order to study the correlation between TBM operating parameters and different lithologic strata,taking a Xinjiang water diversion project as the background,300 m of tunneling parameter data was selected for typical lithologic strata.The correlation between 3 tunneling parameters and 6 lithologic strata was analyzed by using mathematical statistics.By analyzing the correlation among propulsion speed,total thrust and cutter speed under the six types of lithologic strata,the tunneling suggestions were put forward.The results show that the average value of propulsion speed and total thrust varies greatly among different lithologic strata.The cutter speed fluctuates little,and the average difference is small.In siliceous,andesite and tuff strata,the total thrust,cutter speed and propulsion speed are not correlated.In mylonite and sandstone strata,the total thrust,cutter speed and propulsion speed are positively correlated.In cataclastic rock strata,the total thrust is negatively correlated with the propulsion speed.
