Figure Q2(b): Retaining wall
(a) Describe the differences between 'active Rankine state' and 'passive Rankine state'. (4 marks) (b) The 7 m high retaining wall is shown in Figure Q2 (b). Determine; (i) Rankine active and passive force per unit length of the wall together with the location of the resultant force. (8 marks) (ii) Rankine active force per unit length of the wall and the location of the resultant force if the groundwater level was found at 2 m from the ground surface. Given saturated unit weight is 19kN/m3 with a friction angle of 35∘. (13 marks)
