The ultimate bearing capacity qu may be determined using Eq. (12.27) taking into account the eccentricity. It must be ensured that

Base Failure of Foundation (Fig. 19.9) If the base soil consists of medium to soft clay, a circular slip surface failure may develop as shown in Fig. 19.9. The most dangerous slip circle is actually the one that penetrates deepest into the soft material. The critical slip surface must be located by trial. Such stability problems may be analyzed either by the method of slices or any other method discussed in Chapter 10.
