Cylindrical Cavity Expansion in Anisotropic Fine-Grained Geomaterials: Theoretical Solution
This paper presents a novel, exact, theoretical solution for the quasi-static expansion of a cylindrical cavity in anisotropic incompressible fine-grained geomaterials under undrained condition. The solution is based on the rotated and distorted elliptical yield surface of the S-CLAY1 model to account for inherent anisotropic behavior without rotational hardening. The solution is rigorously developed by introducing new stress invariants to deal with the inherent anisotropy. The theoretical solution requires numerical evaluation of a system of three first-order ordinary differential equations. The presented solution is verified against finite element analyses.
