The RFPA2D numerical simulation method is only suitable for studying the uniaxial compression failure process, so it has great limitations. To solve these problems, a new numerical simulation method for rock failure process in offshore area is proposed. The method is based on RFPA2D. Based on this idea, a RFPA3D numerical model is constructed to achieve numerical simulation of rock failure process. By simulating three basic experiments of uniaxial compression, uniaxial tension and shear rupture, the nonlinear stress - strain curves and the series images of damage and failure evolution in the same load stage are obtained. The experimental results show that RFPA3D can be more effective than RFPA2D to simulate the rock failure process in the offshore area, and the effect of the all direction al rock failure in 360° is presented.
