Modeling Slope Anchor Reinforcement Using Enhanced Discontinuous Deformation Analysis Method (EDDA) with Natural Neighbor Interpolation

Abstract:

A new enhanced Discontinuous Deformation Analysis method (EDDA) in conjunction with Natural Neighbor Interpolative (NNI) bases for modeling the system composed of high order deformable solids is developed. The advantages of NNI lie in its efficiency and the interpolative property when employed as the shape functions. The anchor reinforcement algorithm is also implemented in the EDDA for modeling high order deformable solids. The numerical results of simple problems by using the proposed method agree well with the corresponding analytical results, and certain slope reinforcement problems are also simulated with rational numerical results, which verify efficiency and accuracy of the EDDA.
