A reinforced earth retaining wall (Figure 13.27) is to be 10-m-high. Here, Backfill: unit weight, g1 5 16 kN/m3 and soil friction angle, f19 5 348
Reinforcement: vertical spacing, SV 5 1 m; horizontal spacing, SH 5 1.25 m;
width of reinforcement 5 120 mm., fy 5 260 MN/m2; fm 5 258; factor of safety against tie pullout 5 3; and factor of safety against tie breaking 5 3
Determine:
a. The required thickness of ties
b. The required maximum length of ties
