A cantilever sheet pile is driven into a granular soil where the water table is 2 m (L1) below the top of the sand.The properties of the sand are ?' = 40 degrees, ? = 17.5 kN/m3, and ?sat = 17.5 kN/m3. It is proposed to excavate to a depth of 6 m (L) below the ground level.
a.)Determine the actual depth to which the sheet pile must be driven (L+D) , using the net lateral pressure diagram. Note: Dactual = 1.3(Dtheory)
b.) Determine maximum moment and location. Assuming an allowable stress of 170 MN/m2, select a sheet pile from the attached table.
