Paper format: PEO / Engineers Canada National Examinations, May 2014, 07-Str-A3 Geotechnical Materials and Analysis. Three hours, closed book, drawing instruments required, one approved Casio or Sharp calculator. All charts and equations are supplied at the back of the paper (the m–n influence chart, a Newmark chart with $I_N = 0.005$, and a two-page formula sheet). Total value 100 marks over six compulsory questions (20 + 10 + 10 + 20 + 20 + 20). Every question and every sub-part is solved in full below.
Reference texts: Das, Principles of Geotechnical Engineering, 9th ed. (Ch. 2 grain size and gradation, Ch. 6 compaction, Ch. 7 permeability, Ch. 8 seepage and flow nets, Ch. 10 stresses in a soil mass, Ch. 11 consolidation, Ch. 12 shear strength); Knappett & Craig, Craig’s Soil Mechanics, 8th ed. (Ch. 2 seepage and flow-net construction, Ch. 5 shear strength and stress-path plots, Ch. 11 lateral earth pressure); Holtz, Kovacs & Sheahan, An Introduction to Geotechnical Engineering, 2nd ed. (compacted-fill fabric, Proctor behaviour by USCS group); Canadian Geotechnical Society, Canadian Foundation Engineering Manual (CFEM), 4th ed. — the governing Canadian practice document for earth pressures, seepage control and settlement; ASTM D698 / D1557 (Proctor compaction), ASTM D2435 (one-dimensional consolidation), ASTM D4767 (consolidated-undrained triaxial with pore-pressure measurement).
Check — one printing slip in the source, carried as stated. The Question 1 header reads “(4 × 5 = 20 marks)” but five statements (i)–(v) are printed. The solution treats the question as 5 × 4 = 20 marks and answers all five parts; the total of 100 marks over the six questions is unaffected.
