1. Mechanically Stabilized Earth (MSE) Wall Project Geotechnical Design CEG 4801 Fall 2010 Kamal Tawfiq, Ph.D., P.E. Due Date: 9/30/2010

2. A reinforced earth retaining wall is to be 20 ft high. The properties of the backfill material are  kN/m 3 and   . Galvanized steel ties are to be used for the construction of the wall. Design the Reinforcements with FS (B) = 3, FS (p) = 3, f y = 2.4x10 5 kN/m 2 and  tie    The properties of the in-situ soil below the retaining wall are  kN/m 3  , and c = 0. Design the panels and the ties of the wall. W
