The Evaluation of Stability of Rock Mass Slope Based on the Block Theory and DDA Numerical

Abstract:

The instability of rock mass in a large scale is caused by the geological interaction and movement over a long period of time, of which rock mass system cut by structural plane and free surface. Firstly the block theory and Kinematics vector analysis are applied to program the analysis of stability in rock mass slope in order to be fully utilised in the pragmatic constructions. Through Matlab compilation to calculate out the movable blocks then by DDA analysis method to analyse the movable blocks inconsecutively. The resultant force of rock blocks and strain can be solved to measure the stability of rock blocks according to the results.
