**MSE Walls-02: Design the length L of geotextiles for a 16 ft wall. (Revised: Aug.-09) Determine the length L of a geotextile-reinforcing for the 16 foot high temporary retaining wall shown below. Also determine the required vertical spacing of the reinforcing layers S v and the required lap length l l . The geotextile chosen has an allowable strength of σ G of 80 lb/inch, and the available granular backfill has a unit weight of γ = 110 lb/ft 3
