15.14 An anchored sheet pile wall is shown in Figure P15.14. Determine the embedment depth, the maximum bend- ing moment, and the force on the anchor per unit length of wall. Use either FSM (F 1.25) or the NPPM with (FS), = 1.5. Assume the soil above the groundwater to be saturated. 9, = 10 kPa 1 m Coarse-grained soil Anchor block 1 m Yaar = 16.8 kN/m3 , = 24, 8 = 4 m FIGURE P15.14
