摘要:
针对成都富水砂卵石地层盾构施工过程中刀盘刀具磨损严重、结泥饼和地表沉降大等问题,从盾构刀盘结构设计、刀具配置、耐磨保护及刀盘碴土改良等方面入手,对刀盘进行了针对性地改良设计。改良后的盾构刀盘不仅实现了长距离掘进,而且也有效地控制了地表沉降,对类似地层盾构刀盘设计具有一定的指导和借鉴作用。

Abstract:
Problems, including serious cutterhead wearing, cutterhead clogging and ground surface settlement, occur during the EPB shield boring in waterrich sandy gravel strata in Chengdu. As a result, the design of the cutterhead is optimized in terms of cutterhead structure, cutter arrangement, antiwearing protection and ground conditioning. The shield with the optimized cutterhead achieves longdistance boring and good ground surface settlement control effect. The paper can provide reference for the design of the cutterheads of shields boring in similar strata in the future.
Key words: Chengdu Metro, waterrich sandy gravel strata, EPB shield, cutterhead design, ground conditioning
