Various-purpose tunnel construction in Russia uses mostly foreign manufacture equipment. In this respect, the article discusses the problem of Russia’s lack of experience in design of shielded tunnel boring machines. The main technological and design parameters of TBMs to be included in the design calculations are presented. It is emphasized that pattern array of rock-breaking tools on the cutter head in many ways governs the machine efficiency. It is proposed to calculate forces on the TBM cutter head equipped with the constant cross section (CCS) disc cutters using the Colorado School of Mines (USA) model. The essence and relations within this model are described. The aspect of the rock-breaking tool arrangement on the cutter heard is discussed. The negative consequences of wrong or improper choice of a setout, e.g. increased wear of bearing assembly or cutters, are illustrated. The main schemes and relations, that allow proper arrangement of cutters on the cutter head and are applicable in automated design systems, are presented.
