Analytical study of active and passive ground anchors
Anchor has been successively used as an in-situ soil reinforcement for more than two decades. The design of anchors is traditionally performed based only on its pull-out capacity, which ignores the interface interaction between anchor and soil due to relative displacement. This paper provides the analytical solutions based on the linear elastic-perfectly plastic model for the interface between the anchor and soil. The derived analytical solutions include the case of soil movements along the anchor axis and the case of soil movements normal to the anchor axis. It shows that the anchor pull-out behavior is only a special case of the general solution for the anchor subjected to the soil movement along its axis. The parametric study for both actively loaded and passively loaded anchor has been extensively carried out, which provides insights into the interface interaction between the anchor and soil and general guidelines in design of an anchor system.
