摘要

We developed a three-dimensional discontinuous deformation analysis (DDA) theory and computer program to analyze the deformation of rock blocks influenced by discontinuous planes in rock masses. In this, a first order deformation function was made and the potential energyand sub-matrices of a single block and contacts were obtained using this. Contacts between the blocks were classified into 4 categories (vertex-vertex, vertex-edge, vertex-triangle, edge-edge contact) according to their distal ce and position criteria. Using input parameters such as center, normal vectors and the radius of the discontinuous plane the three-dimensional block generation program was developed. In the verification test, two cases were analyzed using the three-dimensional DDA program: two-block sliding (one sliding face), and wedge sliding (two sliding faces). The results showed a good match when compared with those derived from an alternative theoretical analysis. The toppling mechanism (domino effect) was also analyzed and similarly gave good results.
