摘 要：The investigation on the shearing failure strength of discontinuous material such as soil and freshly mixed cementitious material etc. by microscopic approach is presented in this paper. After the behavior of particles in each stress state is examined, the formula for calculating shearing failure strength is induced by considering the balance of forces acting on all particles, to show the influence of mean principal stress and loading speed etc.. Moreover, a series of shearing tests are carried out with fresh mortar to verify the theoretical results after investigating the measuring method for shearing failure strength.
