Finite cavity expansion in dilatant soils: loading analysis

摘要: An analysis of the quasi-static expansion a cylindrical or spherical cavity in an infinite dilatant elastic-plastic soil is presented. Closed form solutions for stress and displacement fields during are given. The modelled as linear elastic-perfectly plastic, using non-associated Mohr-Coulomb yield criterion. explicit solution pressure-expansion relationship obtained with no restriction on magnitude deformation. It found, particular, that radius increases indefinitely pressure approaches finite limiting value. This can be determined analytically help single series. novelty new lies introduction dilation to large strain expansion. Examples implications geotechnical engineering discussed.
