As shown in Figure $1,$ a $45$ cutting slope is excavated to a depth of $8m$ in a

deep layer of saturated clay of unit weight $19k\frac{N}{m^3}.$ The relevant shear

strength parameters are $c_u=65$kPa and ${}_u=0.$ Determine

$($a$)$ Determine the global factor of safety of the slope using Taylor's chart.

$($b$)$ Determine the factor of safety of the slope using the ordinary$/$Fellenius

method and plot the associated critical failure surface.

$($c$)$ Determine the factor of safety of the slope using Bishop's simplified

method and plot the associated critical failure surface.
