Question

Problem No.1 Relevant Information Nine Design aq m high geogrid-reinforced wall where the reinforcement spacing must be at 1.0 m spacing, since the wall facing is of precast segmented concrete facing panel type. The coverage ratio is 0.8 (i.e, geogrids do not cover the3 entire ground surface at each lift, they are slightly separated). The length-to- Ni height ratio of the reinforced soil wall should not be less than 0.7 (i.e., L 4.9 m). Additional details of the problem, including soil and geogrid data are given in the figure 1. q=15 kN/m2 30 u 160 kN/m nRF 4.0 25 a-40 kN/m FS-14 28.6 kN/m C 0.75 Bearing capacity 600 kN/m2
