盾构机盘形滚刀刀圈与地层适应性分析

An Analysis on the Adaptability of the Cutter Head of Disc Cutter of Shield Machine to the Strata

在盾构施工中,对于不同的地质条件,所选择的刀具常常不同,通过对各种不同结构的刀圈破岩机理的分析,结合现场使用的经验,提出不同刀圈所适应的地层,为刀具选型提供理论依据。

During shield construction,cutters selected often change with different geological conditions.By analyzing the rock-breaking mechanism of cuter heads with different structures and in combination with the on-site practice experience,this thesis points out the strata to which different cutter heads adapt,which provides theoretical basis for cutter model selection.
