THE BEHAVIOUR OF ANCHOR PLATES IN SAND

This paper describes a theoretical investigation into the behaviour of anchor plates in sand. Consideration is given to the effects of anchor embedment, friction angle, dilatancy, initial stress state and anchor roughness for anchor plates with either a vertical or a horizontal axis. Collapse loads are observed to increase sensibly with embedment. Deep anchors exhibited high collapse loads. However, because of local yield, the deformations of deep anchors before collapse may be sufficiently large to necessitate the adoption of a practical definition of failure at loads below the actual collapse load. Soil dilatancy and anchor roughness significantly affect anchor capacity for certain cases, but the effect of the initial stress state on collapse load is small for typical cases. The theoretical results are compared with the results of the authors' model tests as well as other model and field test data. There is encouraging agreement and, for the cases considered, the theoretical results provide a reasonable prediction of anchor capacity. The theoretical results for sand are extended to the case of cohesive-frictional soils. The theoretical results are presented in influence charts which may be used in hand calculations to obtain an estimate of anchor capacity for a wide range of geometries and soil types. The use of these charts is illustrated by a worked example. (Author/TRRL)
