Pullout Capacity of Inclined Shallow Single Anchor Plate in Sand

Abstract

Experimental and analytical investigations on the pull-out capacity of inclined shallow strip plate anchors in sand were conducted. Experimentally, a prototype set-up was developed to measure the pull-out load and displacement of anchor plates in dense sand and further to depict the failure mechanism of the anchor and the soil mass. Analytically, the concept of the plastic limit equilibrium method of analysis was used to develop the analytical model that would utilize the failure mechanism observed during the present experimental investigation. In this investigation, the effect of dilatancy for dense sand, plate flexibility, and shape factor were examined. After validating the developed theory with the present experimental results and the available data in the literature, the analytical model was used to develop data for a wide range of anchor inclination/soil/geometry conditions. Design procedure is recommended for the use of practicing engineers.
