- The hydraulic head that would produce a quick condition in a sand stratum of thickness 1.5 m, specific gravity 2.67 and voids ratio 0.67 is equal to
- Clay layer A with single drainage and coefficient of consolidation Cv takes 6 months to achieve 50% consolidation. The time taken by clay layer B of the same thickness with double drainage and coefficient of consolidation Cv/2 to achieve the same degree of consolidation is
- Degree of consolidation is
- For a loose sand sample and a dense sand sample consolidated to the same effective stress
- Within the consolidation process of a saturated clay
- Rise of water table in cohesionless soils upto ground surface reduces the net ultimate bearing capacity approximately by
- Terzaghi’s bearing capacity factors Nc, Nq and Nr are functions of
- Valid range for S, the degree of saturation of soil in percentage is
- If the natural water content of soil mass lies between its liquid limit and plastic limit, the soil mass is said to be in
