为了进一步推进和提高我国大型泥水盾构刀具的使用与管理水平，解决其目前存在的突出问题，以南京长江隧道、南京扬子江隧道、南京地铁3号线和10号线过江单洞双线隧道等大型泥水盾构施工为背景，通过对复合地层盾构掘进施工刀具使用的分析总结，提出了刀具管理的前期设计、过程使用管理、刀具检查更换、意外事故的预防和恢复掘进注意事项等刀具使用系统管理理念，以期为今后类似工程盾构施工刀具管理提供指导与借鉴。

The application of cutting tools of shield in complex strata of Nanjing Yangtze Rivercrossing Tunnels and Nanjing Rivercrossing Metro Line No. 3 and Line No. 10 is analyzed and summarized. And then the initial design, application and management, cutting tool checking and replacing, incident prevention and boring recovery of cutting tool management are proposed, so as to improve the application and management of cutting tools of large slurry shield in China. The results can provide reference for application and management of cutting tools of shield in similar projects in the future.
