A subsurface profile for your site is shown in Figure $1.$ To aid your supervisor, generate

and plot profiles of total vertical stress, vertical and at$-$rest horizontal effective stress, and

pore water pressure with depth. You may assume the soil is fully saturated and use the Jaky

$(1948)$ correlation for the at rest lateral earth pressure coefficient, $K_0=1-sin{}^{\text{'}}$

Soft to med. Stiff tan$-$gray, wet silty

clay $($CL$),=17\mathrm{.}7k\frac{N}{m^3}=18$

Dense, grown$-$gray, wet, gravelly
