Prof. M. Meguid 2008-2009 McGill University DEPARTMENT OF CIVIL ENGINEERING AND APPLIED MECHANICS CIVE 416 - Geotechnical Engineering Assignment No. 3 1. For the retaining wall shown in Figure 1, determine the at-rest lateral earth force per unit meter length of the wall. Also, find the location of the resultant for the following cases: a) H 1 = 2.5 m, H 2 = 2.5 m, q = 0, γ sat = 19 kN/m 3 . The backfill is granular material with c = 0, and φ′ = 30 o . b) H 1 = 6 m, H 2 = 0 m, q = 0, γ = 18 kN/m 3 . The backfill is over-consolidated clay with a plasticity index of 26 and over consolidation ratio of 2. c) Redo case b assuming that the surcharge q = 40 kN/m 2 . Figure 1
