(1) A continuous footing with length of 12 m is built on the soil, which has y = 19 kN/m3.PHI = 28°, e' - 31 kN/m. The depth of embedment (D, ) is 1.5 m and the width (B) of the foundation is 2 m. Using Terzaghi's bearing capacity factors, determine the ultimate bearing capacity (q) and net ultimate bearing capacity (qu(net )) before the general shear failure occurs in soil. (2) Refer to problem (1). If a square footing with dimension 2 m x 2 m is used instead of the wall footing, what is the ultimate bearing capacity (q.) and net ultimate bearing capacity (qu(net ) before the general shear failure occurs in soil.
