CE 728 Geotechnical Earthquake Engineering Department of Civil Engineering Middle East Technical University, Ankara,Turkey Assoc. Prof. Dr. K. Önder Çetin ASSIGNMENT 8 Seismic Assessment of Retaining Structures For the retaining wall shown in the figure given below: Backfill slope 15 derece; surcharge 20 kN/m Hint : φ + - = sin 1 sin 1 A K ; - + = sin 1 sin 1 P K ; A v A A K c K P - = 2 σ ; P v P P K c K P + = 2 a) Determine the active and passive pressures acting on the wall by using Rankine’s theory and plot your results on a similar figure given below. Determine the total resulting force (R) per meter length acting on the wall. Assignment 8 : Seismic Assessment of Retaining Structures 4 m 2 m Sand γ wet =18 kN/m 3 c = 10 φ′ =30 0 Sand γ sat =19 kN/m 3 c = 5 kN/m 2 φ′ =32 0 4 m 2 m
