Design the cantilever sheet pile wall supporting a loose sand fill as shown in the following Figure. The surcharge is equal to 10 kPa. 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 Ka and Kp for the dense sand are 0.2 and 13.125, respectively. a) For a factor of safety of 2 on the passive resistance, determine the required depth of penetration depth, D. (initial trial with D'=4.2m) b) Determine the bending moment of the sheet pile. c) Select a sheet pile section from the Table 9.1 (E=210x10³ MN/m² and fall-210 MN/m²) 7.0m. D 2.0m Yt = 16.5 kN/m³ $' = 30° Loose sand fill: Yt 19.5 kN/m3 $' = 30° Dense sand: Yt = 21 kN/m³ $' = 40° q=10 kN/m²

Question
1. Design the cantilever sheet pile wall supporting a loose sand fill as shown in the following Figure. The surcharge is equal to 10 kPa. GWT is at the same height on both sides, and assume yw=10kN/m³. Based on the log spiral solutions, the Ka for the loose sand is 0.3 while the K₂ and Kp for the dense sand are 0.2 and 13.125, respectively. a) For a factor of safety of 2 on the passive resistance, determine the required depth of penetration depth, D. (initial trial with D'=4.2m) b) Determine the bending moment of the sheet pile. c) Select a sheet pile section from the Table 9.1 (E-210x10³ MN/m² and fall-210 MN/m²) 7.0m. D 2.0m Yt = 16.5 kN/m³ $' = 30° Loose sand fill: Yt = 19.5 kN/m3 $' = 30° Dense sand: Yt = 21 kN/m³ $' = 40° q=10 kN/m²
