摘　　要：为了提高土压(EPB)/隧道掘进机(tunnel boring machine,TBM)双模盾构掘进效率,减少滚刀磨损,以深大城际铁路机场东站—黄麻布站区间为依托,以该隧道左线里程ZDK8+583.0~ZDK8+359.8全断面硬岩掘进段为研究对象,对区间所采用的EPB/TBM双模盾构滚刀性能展开研究。首先,根据滚刀功能和类型的不同,对该区段的滚刀更换情况以及磨损状况进行统计分析,并获得最优性能的滚刀;然后,为更好地指导开仓换刀,以最优性能滚刀为例对滚刀使用寿命进行评估;最后,根据现场实际情况建立刀具信息管理系统。研究结果表明:中铁装备宽刀更适合该类地层的掘进,所搭建的刀具管理系统能很好地实现刀具信息化管理,确保现场施工更经济、高效。In order to enhance the excavation efficiency of an EPB/TBM dual-mode shield machine and minimize disc cutter wear,the study was conducted on the performance of disc cutters along the Intercity Railway from Airport East Station to Huangmabu Station,Shenzhen.The research focused on the full-section hard rock strata from ZDK8+583.0 to ZDK8+359.8 on the left side of the tunnel.Initially,the study analyzed cutter replacement conditions and wear patterns based on different functions and types of disc cutters to determine optimal performance criteria.Subsequently,the service life of the disc cutters under optimal conditions was evaluated to guide replacement scheduling.Finally,a tool information management system tailored to the project’s requirements was established.The findings highlight that China Railway's wide-blade disc cutter is well-suited for excavating this specific formation.The implemented tool management system effectively manages comprehensive information about the tools,which helps ensure cost-effective and efficient onsite operations.This research serves as a practical guide for choosing disc cutters for shield tunneling machines.It promotes better information management practices for disc cutters,leading to safer and more efficient operations.
