A consolidation analogy model is shown in Figure 3 below. Assume that the spring in the figure represents a normally consolidated clay (NC). The water valve is closed in $$\mathbf{A}$$ and $$\mathbf{B}$$, and open in $$\mathbf{C}$$ and D. State your assumptions clearly in your answers if any! (a) Explain the consolidation process for a normally consolidated clay using the models presented in Figure 3 for $$\mathbf{A},\mathbf{B},\mathbf{C}$$ and D. (4 marks) (b) Recommend the type of test and equipment that may be used to determine the shear strength parameters for the loading condition shown in $$B$$ and $$D$$. (4 marks) (c) Explain scenarios that may be encountered in geotechnical practice with an example that is similar to B and D. (4 marks) (d) Comment on the pore-water pressure value for the loading scenario D. Also, discuss whether the soil would have completely drained all of the water (i.e., in the field). Would the soil be still in a state of saturated condition? (3marks)
