A soil profile is shown in the following figure. The GWT is at Im below the ground surface. Layer no Thickness (m) YA Your (kN/m?) (kN/m) 16.3 20 1 0.6 II H-4 0.6 16.3 20 III H-6 1.0 13.0 18.0 Clay Vad The clay is over-consolidated with: oe' =300kPa C=0.5, C-0.1, Cu = 2.0 m/yr Sand layers are assumed to be dry and fully saturated, above and below the GWT, respectively. Yw=9.81kN/m a) Calculate the initial o, u, and o' at the middle of the clay layer. b) If a surcharge, Ao=500kPa, is applied at the ground surface, estimate the corresponding consolidation settlement.(using the stress at the middle of the clay calculated from ()) c) At the end of one year, after the placement of the surcharge, how much primary consolidation settlement would have occurred? d) Also at the end of one year, what would be the "excess" and the "total" pore water pressure at the middle of the clay layer? (note: initial excess pore pressure-A0) Degree of consolidation at a certain depth Average deeree of consolidation 1, UN > . e . 19 ai 0 IEEERR + 15 SY 2 * Step by Step Solution
