B) State whether the sentence is true or false (answer 5 only). 1. The preconsolidation stress seprates between the overconsolidated state and normal consolidated state. 2. The soil may consolidate when the ground water table level rise up. 3. In flownet, the head loss in each drop is constant. 4. In flow net, the equipotential lines represent lines of equal potential. 5. The shear strength of granular material is affected largely by the initial void ratio. 6. Drained triaxial compression test means that the soil specimen is dry.
