[3] A retaining wall has to be designed in order to support a backfill of 7m height. The properties of backfill and soil strata below the retaining wall are given in the figure. Proportion the retaining wall foundation if it has to also support a vertical load of 500kNm. There is no water table present up to the depth of rock strata. The design should consider center of the stem of retaining wall. Assume that the effective area method is applicable for eccentric foundations for all the calculations. Check the design for overturning, sliding. Calculate the ultimate bearing capacity of wall foundation and the factor of safety against shear failure.
