A 4m high vertical wall supports, a saturated cohesive soil (du= 0) with horizontal surface. The top 2.5 m of the backfill has bulk density 17.6 kN/m³ and apparent cohesion of 15 kN/m². The bulk density and apparent cohesion of the bottom 1.5 m is 19.2 kN/m² and 20 kN/m² respectively. If tension cracks develop, what would be the total active pressure on the wall?Also draw the pressure distribution diagram.
