Abstract: Discontinuous deformation and displacement analysis (DDD) is a new way for analyzing the slope failure process, and this method combines the advantage of finite element method of RFPA and discontinuous deformation analysis (DDA) effectively. The problems such as large displacements which cannot be analyzed by RFPA, by the fractured rock initiation, and by propagation process issues which cannot be simulated by DDA, can be solved by DDD. And it also revealed the whole production process of the microscopic crack of the slope until it is destructed. Based on the original method of DDD and conventional centrifugal load test mechanism, it has been converted into a new formation called DDD centrifugal loading. This method not only preserves the feature of the original DDD, but also attains the instability sliding surface of the slope. Based on the DDD centrifugal loading method, the sectional slope of west slope of the Heishan Iron Mine and determination of caving in actual working conditions that establish a two-dimensional model of the slope with hole. It simulated mechanism of the sliding slope with hole under the presence or absence of the anchor and it also analyzed the evolution of the shear process from microscopic cracks to macroscopic damage, the safety factor and the vertical and horizontal displacement vector. The results show that:the caving hole of the convex corners area of the slope is a key point of stress concentration, and there is a significant effect of tension on slope instability and failure process which got a good agreement with the actual provision of the slope. Although the anchor disperses stress concentration effectively, improves the safety factor of the slope, and reduce the displacement, it still has the possibility of destruction and need to observe continuously.
