5- There will be two distinct shear stress limits (i.e. peak and ultimate shear strength) for: (a) Dense Sand (b) Loose Sand (c) None of above 6- Which test is more suitable to analyse the short-term behaviour of a foundation on a saturated clay (a) Consolidated Drained test (b) Unconsolidated Undrained test (c) Unconfined Compression test (d) None of the above 7- In a triaxial test for the normally consolidated clay, chamber confining pressure = 150 kN/m2 and deviator stress = 250 kN/m2. What is the effective major principal stress? (a) 400 kN/m2 (b) 150 kN/m2 (c) 100 kN/m2 (d) 250 kN/m2 8- Friction angle of dry sand is 35º. In a direct shear test on this sand, a normal stress of 200kPa was applied. What shear stress will cause the failure? (a) 200kPa (b) 140kPa (c) 285kPa (d) 105kPa 9- What is the definition of compression index of soil? (a) Incremental stress divided by incremental strain (b) The slope of void ratio-log effective stress plot after past maximum vertical stress (c) The slope of void ratio-log effective stress plot before past maximum vertical stress (d) Incremental strain divided by incremental stress 10- A clay layer (double drainage) of 20+ X m thickness showed 10mm settlement after 200 days. What is the degree of consolidation of clay soon after load applied (at time=0) ? (a) 50% (b) 100% (c) 0% (d) 25 % 4
