... of plate anchors in sand has been investigated by numerous researchers. Elastoplastic finite element analysis and experimental studies have been done by Rowe and Davis (1982), which proposed the bearing capacity factor as a function of orientation, the friction angle, dilation angle, embedment ratio...

... the edges of the anchor to the soil surface. No obvious shear band was observed around the anchor when the anchor embedment ratio is large than 7. The effect of relative depth (depth/width) and width of anchor are discussed. In the range of this study, the model scale has minor effect on the normalized...

... ABSTRACT In this paper, finite element analyses of plate anchor keying in Normally Consolidated (NC) clay were performed. Bearing capacity of plate anchors was investigated with various embedment ratios and pullout inclination angles. Both vented anchor base (no suction on rear face) and fully...
