A point A in a clay layer, the initial stress conditions are as follows:

$\backslash$sigma z$=\backslash$sigma $1=1800$psf

$\backslash$sigma h$=\backslash$sigma $3=1300$psf

uo $=800$psf

when a stress q $($unit pressure applied at the surface$)$ is applied to the surface, the stress increase

at point A is as follows:

$\backslash$Delta $\backslash$sigma z$=0\mathrm{.}4$q$,$ and $,\backslash$Delta $\backslash$sigma h$=0\mathrm{.}5\backslash$Delta $\backslash$sigma z$=0\mathrm{.}2$q

From lab tests on the clay layer, the pore pressure coefficients were estimated to be B$=1$ and

A$=0\mathrm{.}8.$ Plot the total and effective stress paths for the following scenarios:
