(1b) A retaining wall is 7.25 m high. Soil supported consists of 4.5 m of sand (Density (1700 +2N*) kg/m°, =35°) overlaying a saturated sandy clay (density (1825+N*) kg/m°, 0 = 30°, c=(16+0.02N*) kN/m²). The ground water table is at the upper surface of the sandy clay. Make a sketch of the distribution of active pressure on the wall stating the principal values. Calculate the thrust per linear meter of the wall, neglecting cohesion and frictional force on the back of the vertical wall.
