The load–deflexion charateristics of a deep rigid anchor in an elastic medium

The axially symmetric problem of an infinite elastic solid containing a bonded symmetrically loaded spheroidal rigid inclusion is considered. This problem is of interest in connexion with the geotechnical study of the time-independent, load–deflexion characteristics of deep rigid anchors embedded in cohesive soil or rock media. The solution to the deep rigid anchor problem is obtained by making use of Boussinesq's three-function approach applicable for the rotationally symmetric problem in the classical theory of elasticity. Load–deflexion relationships for rigid anchors of both prolate and oblate spheroidal shapes are presented in exact closed form. By treating the single anchor as a solid of revolution it is possible to investigate the influence of various geometric aspect ratios. From the exact load–displacement relationships presented here it is possible to recover solutions to anchors with spherical, circular or elongated shapes simply as limiting cases.
