5) a) Estimate the quantity of seepage (in m³/day per metre run) emanating from the downstream side of the sheet pile wall shown in Figure Q5a. The coefficient of permeability (k) for the soil is 2.5 x 107 m/s. b) Calculate the factor of safety against piping due to heave for the sheet pile wall shown in figure Q5a. Hence, if the water level in front of the wall dropped to ground level, calculate the revised factor of safety and comment on the acceptability of both results. Assume n = 0.41 and G₁ = 2.7 for the soil. c) If the unit weight of the soil is 20 kN/m³, calculate the effective stress at "A" the toe of the sheet pile wall Sheet piling W.T. 6.50 m WT TA. 4.70 m 4.80 m 1,20 m Figure Q5a 20 m
