Effect of Rock Properties on Rock Breaking with the Tunnel Boring Machine

Abstract
To enhance w orking efficiency of the tunnel boring machine( TBM) and to extend w orking life of the disc cutter,effect of rock properties on rock breaking w ith TBM is studied. Regarding the disc cutter and the rock as a w hole body,stress distributions of the rock and the disc cutter during rock breaking process are simulated numerically. At the same time,stresses in the disc cutter and cutting-in in the rock are also measured. Effects of...
