Popis:	As the country’s underground tunnels continue to expand, underground construction technology has been developed rapidly. In order to meet the development needs of construction technology in China, Tunnel Boring Machine (TBM) has made great progress due to its own advantages. In this paper, feed amount of disc cutter on rock crushing under complex working conditions is considered. The mechanism of rock fragmentation is analyzed. The force between disc cutter and the rock is studied. The accuracy of the model is verified by setting up a TBM rock fragmentation experiment platform. This study provides technical support for TBM construction parameters under different working conditions.
