Foundation engineering $-$ HWI

$2\mathrm{.}12$ Refer to the soil profile shown in Figure P$2\mathrm{.}12.$ Determine the total stress, pore water pressure, and effective stress at $A,B,C,$ and $D.$

$4\mathrm{.}1$ For the following cases, determine the allowable gross vertical load$-$bearing capacity of the foundation. Use Terzaghi's equation and assume general shear failure in soil. Use FS $=4.$
