Consider the retaining walls in Figures la and lb.
(i) The retaining wall in Figure la is unyielding (i.e. the wall does not translate or rotate) and
there are no lateral strains in the ground. Draw the Mohr Circle that represents the stress
state of Soil A. Be sure to label your plot and include the Mohr-Coulomb failure envelop.
(ii) The retaining wall in Figure Ib moves away from the backfill. Based on Rankine's earth
pressure theory, derive the coefficient of earth pressure for Soil A. Draw the Mohr Circle
for this new stress state of Soil A on the same plot from (i),
(a)
(b)
