The Integration of Numerical Methods of Discontinuous Deformation Analysis (DDA) and Discontinuous Displacement Method (DDM) for Jointed Rock Slope Stability (Case Study: Tectonic block 4 Choghart Mine-Bafgh)

Due to technological progress and consequently the development of numerical methods in solving problems, numerical methods have found a special place in various sciences especially rock mechanics. Numerical methods can be used according to the type of medium used as a combination that so-called hybrid methods. According to studies on slope stability analysis, displacement discontinuity method for crack growth and discontinuous deformation analysis method for modeling large displacements as combination was found suitable. Hence first by providing flowchart of how the combination of these two methods, with geometrical modeling using random disks method and infinite joints method in the program coding in the Mathematica environment, to crack growth in the geometrical model created by random discs coded in the Mathematica program deals and finally, stability analysis was conducted in the DDA and UDEC software. It is worth mentioning, the case studies used in this study was tectonic block 4 Choghart and according to the comparison be made can clearly capabilities discontinuous deformation analysis method than the discrete element method in modeling large displacements observed. It is worth mentioning that crack growth creates geometric model is different and follow different results in the slope stability analysis.
