Abstract
The performance of rectangular plate anchors in normally consolidated (NC) clay has been studied using three-dimensional large deformation finite element analysis. The large deformation FE method has been extended from 2D to 3D case to study the effect of anchor shape. The large deformation analysis is based on mesh regeneration and interpolation of stresses and material parameters, in which a modified "Recovery by Equilibrium in Patches technique" is developed to improve the accuracy of stress mapping. Anchors with a range of aspect ratios were modelled under no-breakaway and immediate breakaway conditions, using small strain and large deformation FE methods. It was found that the anchor aspect ratio has a significant effect on anchor capacity. However, the soil strength gradient, k, has no effect on anchor capacity in the range of k = 1 to 3 kPa/m. The depth at which separation between soil and anchor occurs was found to be deeper for normally consolidated soil with strength proportional to depth than for uniform strength soil
