6.1 Consider a clay layer drained at the top and bottom as shown in Figure 6.3a. For the case of constant initial excess pore water pressure (u; = 0) and T, = 0.4, determine the degree of consolidation U at z/H, = 0.4. For the solution, start from Eq. (6.32). 6.2 Starting from Eq. (6.34), solve for the average degree of consolidation for linearly varying initial excess pore water pressure distribution for a clay layer with two-way drainage (Figure 6.3d) for T = 0.6. m=00 2 M Mz sin exp(-MT) H 0 = 1- m=0 m=00 2 Uay = 1 - M m=0 exp(-MT) (6.32) (6.34) 6.1 Consider a clay layer drained at the top and bottom as shown in Figure 6.3a.
