Tunnelling and Underground Space Technology
With the wide application of large-diameter tunnel engineering in complex stratum, the rock-breaking efficiency of shield cutter has become a key factor restricting the tunneling efficiency. Most of the existing studies focus on the force and spacing optimization of single-edged disc cutters, and the systematic analysis of the coupling mechanism ...
