Analyze the uplift resistance of circular plate anchor in non-homogenous and anisotropic clays using NGI-ADP material model

Abstract

The paper analyzes the uplift resistance of circular plate anchor in non-homogenous and anisotropic clays using NGI-ADP material model. The finite element model is implemented by Plaxis 2D V2020. The effect parameters on uplift resistance of plate anchor in nonhomogenous and anisotropic clays, i.e embedded depth of anchor (H), non-homogenous ratio (m), anisotropic ratio (r_e), are considered in analysis process. The uplift resistance of plate anchor is determined by resistance factor N. The results show that, the resistance factor N increase by increase of ratio between H and diameter of plate anchor (H/D) and decrease when r_e decrease. the resistance factor N is also decrease by increase of m. However, the uplift resistance of plate anchor is still increase by increase of m. Besides, The ANN (Artificial neurons network) model is applied in this study based on data from finite element analysis results. With architecture of ANN is 3-10-1, the predict results from ANN give well agreement with results from finite element analysis.
