Compare the values of active and passive earth pressures, Civil Engineering

Assignment Help:

A retaining wall 12 metres high is proposed to hold sand. The values of void ratio and φ in the loose state are 0.63 and 30° whereas they are 0.42 and 40° in the dense state. Suppose the sand to be dry and that its grain specific gravity is 2.67, compare the values of active and passive earth pressures in both the loose and dense states.
