CVE$363-$ SOIL MECHANICS

$2020-21$ SPRING

Final Exam $-$Q$4$

$4-$ A retaining wall and the retained soils are shown in Figure Q$3,$ below.

Figure Qs

$($a$)$ Calculate and plot the distribution of vertical total stress, ${}_v^{\text{'}},$ pore water pressure, $u$ and vertical effective stress, ${}_v^{\text{'}},$ within the soils shown above.

$(10$ Pt$)$

$($b$)$ If the horizontal effective stress within the soil at the back of a retaining wall is given by the equation:

${}_h^{\text{'}}=K_a{}_v^{\text{'}}$

Calculate and plot the distribution of horizontal effective stress, ${}_h^{\text{'}},$ pore water pressure, $u$ and horizontal total stress, ${}_h$ acting on the back of the wall, using the values of $K_a$ given in Figure Q$3,$ above.
