Abstract:

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.

Key words: shield machine, disk cutter, cutter head
