摘　　要：文章针对杭州地铁SG3-8标段工程香积寺路站—大关站区间需要切磨约312根直径377mm的钢筋混凝土桩基,对盾构刀具切磨钢筋混凝土桩基切削机理进行了模拟,分析了刀具前角、刃角对钢筋及混凝土切削过程的影响,有效指导了盾构刀具的选择及配置,顺利穿越了群桩区段。Aiming at the section from Xiangjisi Road Station to Daguan Station of Hangzhou Metro SG3-8 project,about 312 reinforced concrete pile foundations with a diameter of 377mm need to be cut,the cutting mechanism of reinforced concrete pile foundation with shield cutting tools is simulated,and the influence of the cutting Angle and edge Angle of the tool on the cutting process of steel and concrete is analyzed,which effectively guides the selection and configuration of shield cutting tools,passed through the pile group section smoothly.
