Estimate the total consolidation settlement (primary & secondary) after 2 years and 9 months after the completion of primary consolidation settlement of an over consolidated clay layer under the bridge pier as shown below. The pier's dimensions are (2 m x 3 m). Use Yw= 10 kN/m and note that the time for completion the primary consolidation is 3 years. | Qo= 960 kN 111 G.W.L 1 m Sand Ya=16.5 kN/m? 2 m Ysat = 18 kN/m3 Silty Sand Ya=17.5 kN/m 3 m Ysat = 18.5 kN/m3 Clay Ya=20 kN/m , ysat = 21 kN/m3 e, = 0.6 , Ae=0.04 , o= 78.3 kN/m2 4 m Cc= 0.4, Cs= 0.1, Ca= 0.02
