摘要： 以东莞新源路站—东城南站区间盾构隧道为工程背景，基于现场监测数据，运用数理统计手段，系统探讨了土压平衡盾构机6个关键掘进参数与4类不同风化程度花岗岩地层之间的关联特性。研究结果表明：①花岗岩地层的不同风化程度是盾构掘进参数的一个重要影响因素，不同地层的掘进参数有着不同的规律。②花岗岩地层种，盾构总推力与刀盘贯入度倒数呈现较强线性相关关系；掘进速度和刀盘贯入度呈现强线性相关关系；刀盘扭矩和土仓压力不存在明显的相关性。研究的相关成果，对在花岗岩残积土地层中采用同类型盾构的工程项目，其掘进参数的合理选取与优化调控具有指导意义。

Abstract: This study examines the shield tunnel between Xinyuan Road Station and Dongcheng South Station in Dongguan as the engineering background. Using field monitoring data and statistical analysis methods, it systematically investigates the correlation characteristics between six key EPB shield tunneling parameters and four categories of granite strata with different degrees of weathering. The results show that: (1) The degree of granite weathering is a major factor influencing shield tunneling parameters, and each stratum exhibits distinct parameter patterns. (2) Within granite formations, the total thrust of the shield machine shows a strong linear correlation with the reciprocal of cutterhead penetration; the advance rate and cutterhead penetration also exhibit a strong linear correlation; meanwhile, cutterhead torque and chamber pressure show no obvious correlation. The findings provide guidance for the reasonable selection and optimization of tunneling parameters for similar shield machines operating in granite residual soil strata.
