A 5 m deep excavation is required in a dry sand where = 17.5 kN/m 3

Question:

A 5 m deep excavation is required in a dry sand where γ = 17.5 kN/m3 and ϕ' = 32° (see Figure 18.11). Determine the actual depth to which the sheet pile has to be driven and the required section (from Table 18.1), assuming allowable stress of 190 MN/m2. Use the net pressure diagram.
