Kinematic limit analysis of pullout capacity for plate anchors in sandy slopes

The pullout capacity of plate anchors has been studied extensively over the past 40 years. However, very few studies have attempted to calculate the pullout capacity of anchors in sandy slopes. Inthis paper, three upper bound approaches are used to study the effect of a sloping ground surface and frictionangle on pullout capacity and failure of plate anchors. This includes the use of; simple upper boundmechanisms; the block set mechanism approach; and finite element upper bound limit analysis. The aim ofthis research is to better understand the various failure mechanisms and to develop a simple methodology forestimating the pullout capacity of anchors in sandy slopes.
