APPLICATION OF DDA METHOD IN STABILITY ANALYSIS
OF TOPPLE ROCK SLOPE
|
|
|
|
|
Abstract Limit equilibrium analysis method is not suitable for the stability analysis of topple rock slope. At present， the G-B method put forward by Goodman and Bray is widely applied for the analysis of this kind of rock slope. However its rationality needs to be evaluated. The discontinuous deformation analysis (DDA) method is adopted to analyze the deformation and failure mechanism of a typical example of topple rock slope. Contrast analysis results show that G-B method will give unreasonable results.
