Three-dimensional numerical manifold method simulations for blocky rock analysis

Abstract

After decades of development, people realize that there are wider and more various applications of numerical modeling and analysis. However, current feasible software tools cannot satisfy engineering and commercial goals. Therefore, a new generation of numerical modeling and analysis is imminent. The implemented software tool is based on the 3-D version of the Numerical Manifold Method (NMM). Due to extremely complex situations caused by concave blocks, new and improved algorithms based on existing algorithms are implemented. Besides, in order to satisfy engineering requirements, support design based on block theory is also implemented. Sufficient examples are elaborated in this report in order to illustrate the strength and feasibility of the proposed 3D-NMM software as if compares to current software tools. Moreover, various examples with further vertical and parallel development are needed in order to improve accuracy and efficiency.
