Stability of an unsupported vertical circular excavation in clays under undrained condition
AbstractBy using the axisymmetric finite elements static limit analysis formulation, proposed recently by the authors, the stability numbers (γH/co) for an unsupported vertical circular excavation in clays, whose cohesion increases with depth, have been determined under undrained condition; γ=unit weight, H=height of the excavation and co=cohesion along ground surface. The results are obtained for various values of H/b and m; where b=the radius of the excavation and m=a non-dimensional parameter which accounts for the rate of the increase of cohesion with depth. The values of the stability numbers increase continuously both with increases in H/b and m. The results obtained in this study compare well with those available in literature.
