... ABSTRACT This study used Discontinuous Deformation Analysis (DDA) to investigate slope stability problem. The results suggested that, two shape factors must be considered for block stability on sliding surface, one is sphericity, the other is the ratio of contact length over block perimeter (C...

... ABSTRACT This paper presents the use of the discontinuum approach based on the Discontinuous Deformation Analysis (DDA) for the modeling of granular debris flows which are found to be the major type of the debris flow in Taiwan. Differing from the conventional continuum-based method which...

... ABSTRACT Unstable precursors, such as ground subsidence and thrust, occurred on the lower slope of the Chiu-fen-erh-shan landslide in November, 2002. This study presents the results of applying Discontinuous Deformation Analysis (DDA), which is a dynamic discrete numerical analysis method...

... ABSTRACT In this study, a new numerical model based on Discontinuous Deformation Analysis (DDA) is proposed. By using the proposed numerical model, deformations in foundation of seawall can be simulated. Deformable particles are generated to simulate the deformation characteristics of soils...
