On the Loads for Strength Design of Cutterhead of Full Face Rock Tunnel Boring Machine

Abstract Cutterhead loads are the key mechanical parameters for the strength design of the full face hard rock tunnel boring machine (TBM). Due to the brittle rock-breaking mechanism, the excavation loads acting on cutters fluctuate strongly and show some randomness. The conventional method that usi...
