摘　　要：研究根据刀盘工作地区的地质情况,对盾构机进行选型,盾构机的刀盘基本结构设计是选型的核心,不合理的选型会造成盾构掘进困难。研究结合穗莞深城际施工过程中遇到的盾构机中心刀具异常磨损严重等问题,在常压开仓条件下对刀盘进行针对性改造优化,以增加其适应性。According to the geological condition of the cutter head working area,the cutter head basic structure design of the cutter head is the core of the selection,unreasonable selection will cause the difficulty of the shield tunneling.In view of the severe abnormal wear of the center tool of shield tunneling machine encountered in the process of Suiguanshen intercity construction,targeted transformation and optimization of cutter head under the condition of atmospheric pressure opening are carried out to increase its adaptability.
