The Strain Path Method (SPM) is presently the most realistic theoretical model available for predicting the disturbance to a clay soil caused by the installation of a pile or penetrometer. The method is based on the analogy that a penetrometer pushed into the ground can be modelled as fixed body located within an ideal inviscid fluid flow. The model assumes that the soil deformation is independent of its shearing characteristics and consequently a single flow solution, that of an ideal inviscid flow, is deemed satisfactory to predict soil movements. This paper examines the effect of assuming a flow that is not ideal and investigates the influence of viscosity and boundary conditions on predicted soil strain fields. A variety of solutions are presented for a penetrometer with a 60° conical tip. These facilitate an assessment of the implications of the SPM solution and, following appropriate experimental observations, will allow deduction of more realistic strain fields around penetrometers.
