摘要：

盾构施工过程中由于盾壳摩擦等诸多因素，导致施加在工作面上的有效推力往往小于液压油缸实际提供的总推力，而对于有效推力的准确评估能够有效提升盾构施工的稳定性及经济性，但相关的研究成果依旧匮乏。为了更准确地预测硬岩地层中盾构施工时工作面所受有效推力以及刀盘滚刀切削速率，基于 Ylvie 模型考虑地层特性建立了矩阵形式的分析框架以及预测模型。在盾壳摩擦损耗预测中将 Ylvie 模型与 Heikal 模型进行了对比，在切削速率预测中与 Gehring 和 CSM 模型进行了对比分析，验证了所构建的预测模型的准确性。分析结果表明，研究区间的盾构施工过程中，盾壳摩擦对总推力的损耗达到 41%.

Due to many factors such as shield friction during shield construction, the effective thrustapplied to the working face is often less than the total thrust actually provided by the hydraulic cylinder.Accurate evaluation of the effective thrust can effectively improve the stability and economy of shieldconstruction, but relevant research results are still scarce. In order to more accurately predict theeffective thrust on the working face and the penetration rate of the cutterhead during shield construction inhard rock formations, a matrix analysis framework and prediction model were established based on theYlvie model considering the formation characteristics. The Ylvie model was compared with the Heikalmodel in the prediction of shield friction loss, and compared with the Gehring and CSM models in theprediction of penetration rate,verifying the accuracy of the prediction model constructed in this paper.The analysis results show that during the shield construction in the study area, the loss of total thrust dueto shield friction reached 41%.
