摘　　要：硬岩隧道掘进机(Tunnel boring machine,TBM)是用于隧道一次成型的大型装备。为分析地质条件、掘进状态等关键工程因素对装备掘进功率的影响规律并建立预估模型,首先对装备掘进过程的力学特征进行分析,抓住影响装备掘进过程的主要因素,推导出掘进推力和刀盘驱动扭矩表达式。基于输入能耗与载荷间的依存关系,建立了装备掘进功率的近似预估模型,并结合工程数据识别反映具体工况等因素的模型系数。进一步利用未参与建模过程的独立检验数据对所建立模型的有效性和适用性进行讨论。模型预测值与工程实测值的对比结果表明,建立的掘进功率近似力学模型能够综合反映操作参数、地质参数等关键因素的影响规律。Tunnel Boring Machine（TBM） is a large equipment used in tunnelling construction. In order to analyse the influence of main factors such as geological parameters and operating condition to boring power, the mechanical characteristics of driving process are studied. The thrust and the cutter disc drive torque are obtained by main factors affecting the tunneling process. Based on the relationship between input energy consumption and load, the approximate estimation model of boring power is established. Moreover, engineering data is used to identify the coefficients of the model, which depend on specific conditions. Furthermore, the applicability and effectiveness of the model are discussed with independent data which is not used in modeling process. The comparison between measured and predicted values shows that the proposed model can reflect the influences of the key factors such as operating status, geological parameters.
