Validation for rock block stability kinematics and its application to rock slope stability evaluation using discontinuous deformation analysis
This paper firstly introduces the process in calculation of the contact forces between blocks, and presents a method about the safety factor calculation in DDA. Based on this, the stability validation with a rock block sliding along a double incline has been carried out. Two cases, one with the friction angle (φ), and the other with the friction angle (φ) and cohesion (C) together, are considered. At last, as an engineering application example, DDA method has been used to analyze the stability of a slope with a weak fault controlled in one hytro-project, and it has been shown that as the contact force calculation in DDA method is based on the rigorous equilibrium equations, DDA method may provides a more reasonable method for stability analysis in rock engineering.
