2. Design the anchored sheet pile wall supporting a loose sand fill as shown in the following Figure. GWT is at the same height on both sides, and assume yw=10kN/m³. Based on the log spiral solutions, the K, for the loose sand is 0.3 while the K₂ and Kp for the dense sand are 0.2 and 13.125, respectively. Using the free earth support method, do the following: a) For a factor of safety of 2 on the passive resistance, determine the required depth of penetration depth, D. (initial trial with D'=1.5m) b) Determine the bending moment and the anchor load. c) Select a sheet pile section from the Table 9.1 (E-210x10³ MN/m² and fa-210 MN/m²)

2. Design the anchored sheet pile wall supporting a loose sand fill as shown in the
following Figure. GWT is at the same height on both sides, and assume yw=10kN/m³.
Based on the log spiral solutions, the K₂ for the loose sand is 0.3 while the K₂ and Kp
for the dense sand are 0.2 and 13.125, respectively. Using the free earth support
method, do the following:
a) For a factor of safety of 2 on the passive resistance, determine the required depth of
penetration depth, D. (initial trial with D'=1.5m)
b) Determine the bending moment and the anchor load.
c) Select a sheet pile section from the Table 9.1 (E-210x10³ MN/m² and far-210 MN/m²)
3. Re-design the wall using the fixed earth support method and comment on the
different results from the two methods.
