Abstract: Based on the interface stress element model for discontinuous medium of deformable body, a new numerical model is proposed for anchored rock mass in this paper. The model can fully imitate all kinds of reinforcing bolts that have complex geometry distribution. No limitations are required on the position, length, direction, angle of reinforcing bolts. The results of the numerical analysis employed show that the present model can describe clearly the behavior of rock mass and is promising for engineering application.
