U dr 2.5 A soft soil is to be subjected to preloading using a system of PVD. Excess pore pressure is being drained vertically and radially. The waiting period, PVD, installation and configuration parameters, the consolidation properties of the soil are shown in the tables above. Complete the blanks and compute Uv, Ur and overall U for the system at the end of the waiting period if the PVD spacing, dr, is as shown above. a. 0.609, 0.563, 0.829 6.0.609 . 0.563 0.841 0.677 0.507, 0.841 O d. 0.677. 0.563, 0.859
