摘　　要：针对大直径盾构机在复杂地质条件下的常压与带压换刀技术进行系统对比分析,基于某特大型市政隧道工程案例,详细探讨两种技术在实际应用中的效率、安全性、成本效益、施工质量以及进度影响等方面的差异。通过对比分析得出,常压换刀技术在地质条件稳定的情况下具有操作简便、成本低廉的优势,但在高水压或软弱地层中表现出显著不足。相比之下,带压换刀技术虽初期投入较高、操作复杂,但在复杂地质条件下展现出更高的适应性,尤其在确保施工安全性与提高隧道施工质量方面具有显著优势。该研究结果为复杂地质条件下的盾构施工技术选择提供了重要参考。Based on the case of a large municipal tunnel project,the differences in efficiency,safety,cost effectiveness,construction quality and schedule impact of the two technologies in practical application are discussed in detail.Through comparative analysis,it is concluded that the normal pressure tool changing technology has the advantages of simple operation and low cost under stable geological conditions,but it shows significant shortcomings in high water pressure or weak formation.In contrast,although the initial investment is high and the operation is complex,the tool changing technology with pressure has shown higher adaptability under complex geological conditions,especially in ensuring construction safety and improving the quality of tunnel construction.The research results provide an important reference for the selection of shield construction technology under complex geological conditions.
