A vertical retaining wall $6$ m high is supporting soil which is saturated and has a unit weight of $22\mathrm{.}5$ kN$/$m$3.$ The angle of shearing resistance of the soil, $=35\backslash$deg and the surface of the soil is horizontal and level with the top of the wall. A groundwater level has been established within the soil and occurs at a level of $2$ m from the top of the wall. Using the Rankine theory and consider $1$ m width of wall.
