Study on the Impact of Lateral Pressure on Jointed Rock Mass with DDARF Method

Abstract:

The discontinuous deformation analysis for rock failure (DDARF) method is adopted to simulate the biaxial compression test under different lateral pressure conditions. Then this paper analyzes the impact of the lateral pressure on the specimen failure rules. The simulation results show that the lateral pressure has obvious inhibiting effect on the expansion of wing cracks, crack initiation stress, and specimen peak strength.Keywords: Multi-joint specimen; DDARF method; Lateral pressure; Biaxial compression test simulation
