Determine the magnitude of active and passive earth pressure on the retaining wall, as illustrated in Figure 1. Hence, determine the factor of safety against overturning and the magnitude and position of the resultant of all the forces acting on the wall. Given: Angle of internal friction of the soil Specific Gravity Void Ratio 30 Degrees 2.65 0.5 Psat G,+e 1+e weight unir Assume the soil is saturated. However, ignore water pressures on the wall (assume water table is well below the base of the retaining wall. 0.5m I- 6.5m 2m 3m Not to Scale Figure 1. Retaining Wall, pivoting about point P (14 marks) [20/60 Marks]
