The present study reveals the effect of interaction of two closely spaced shallow circular plate anchors embedded in a homogeneous medium-dense sand bed subjected to identical loading conditions. The investigation has been carried out in a large scale laboratory testing facility where the size of the anchor plates is deployed in the range analogous to that generally used in the real field situation. It can be deduced that at a closer spacing between the anchor plates the uplift capacity of the anchors decreases as compared to that of an isolated anchor. This phenomenon is due to the intervention and coalescence of the failure plane of an anchor in the presence of the other anchor in its vicinity. The dimensionless uplift capacity factor has been introduced in order to understand the interaction phenomenon of two closely spaced anchor plates and its adverse effect on the design philosophy.
