Q-4: The following figure shows the flow net for seepage of water around a single row of sheet piles driven into a permeable layer. Calculate how deep the sheet pile should be driven (h) to achieve factor of safety = 3 against downstream heave, given that ysat for the permeable layer = 18 kN/m3. (Note: Thickness of permeable layer T = 18 m) H₁ = 10 m (h) Heave zone Sheet pile ►||1| Impermeable layer H₂ = 2 m Ysat 18 kN/m³
