This paper presents the preliminary results of an investigation into the behaviour of drag anchors in soils consisting of normally consolidated clay overlying silica sand. A limit equilibrium approach examines the forces acting on an anchor in a pre-ultimate state. This approach is combined with a kinematic model utilising incremental displacements and energy methods, resulting in a simulation program that predicts anchor behaviour in layered soil profiles. The results of this investigation are compared with the results of a series of centrifuge model anchor tests.
