The normal force, circumferential force, side force and inertia force probed are discussed and their corresponding mechanics formulas are presented. A balancing theory of forces acting on cutter head of TBM during rock breaking is put forward and a mathematical mechanical model of disc cutter layout is set up. A typical case with some imported TBM justifies the correctness of the mathematical mechanical model and its solution. Therefore an applicable approach to the layout of TBM disc cutter is developed.
