Clay layer (A) with single drainage of consolidation $$C_v$$ 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 $${\mathrm{C}}_{\mathrm{v}}/2$$ to achieve the same degree of consolidation is Select one: 6 months 24 months 12 months 3 months A soil has bulk density $$3\mathrm{g}/{\mathrm{cm}}^3$$ and water content $$13\%$$, the dry density of the sample is $$\mathrm{g}/{\mathrm{cm}}^3$$ ? $$1.41$$ $$2.91$$ $$2.65$$ $$11.50$$ In an undrained triaxial test, a specimen of saturated day fails under the deviator stress of $$19\mathrm{kg}/{\mathrm{cm}}^2$$ when the cell pressure is 12 $$\mathrm{kg}/{\mathrm{cm}}^2$$. What is the undrained shear strength of the specimen? $$\left(\mathrm{kg}/{\mathrm{cm}}^2\right)$$ 035 $$0.95$$ $$1.55$$ $$0.70$$
