Plot the earth pressure diagram for the $12$ mm thick sheet pile $($ Z$-$ section$)$ and compute the resultant force and its location for the sheet pile system and also name each layers soil type. The data for the layers are : Layer $1$: Angle of internal friction $=32$ degree Unit weight $=17\mathrm{.}2$ KN$/$m$3$ Saturated Unit weight $=18\mathrm{.}7$ KN$/$ m$3$ Void ratio $=0\mathrm{.}78$ This layer is $(0\mathrm{.}80+0\mathrm{.}90)$ m thick $.$ From upper layer there is a GWT from $0\mathrm{.}80$ m down and continued to the bottom $.$ Layer $2$: Angle of internal friction $=0$ Cohesion $=50$ kPa Unit weight $=16\mathrm{.}5$ KN$/$m$3$ Saturated Unit weight$=17\mathrm{.}6$ KN$/$m$3$ Cc $=0\mathrm{.}156$ This layer is $1\mathrm{.}30$ m thick Layer $3$: Angle of internal friction $=14$ degreeCohesion $=30$ kPa Unit weight $=18\mathrm{.}4$ KN$/$ m$3$ Saturated unit weight$=20\mathrm{.}1$ KN$/$m$3$Cc $=0\mathrm{.}110$ This layer is $3\mathrm{.}00$ m thick Layer $4$: Angle of internal friction $=33$ degree Cohesion $=5$ kPa Unit weight $=18\mathrm{.}0$ KN$/$m$3$ Saturated unit weight $=20\mathrm{.}4$ KN$/$m$3$ Void ratio $=0\mathrm{.}66$ This layer is $2\mathrm{.}5$ m thick Layer $5$ : Angle of internal friction $=38$ degree Unit weight $=17\mathrm{.}7$ KN$/$m$3$ Saturated unit weight $=19\mathrm{.}5$ KN$/$m$3$ Void ratio $=0\mathrm{.}58$ This layer is $2\mathrm{.}5$ m thick Left side of the sheet pile $,$ there is nothing from elevation level to $4\mathrm{.}20$ m $.$ Right after $4\mathrm{.}20$ m to the bottom there is a GWT $.$ The dredge line starts from $1\mathrm{.}8$ m below the GWT$.$
