A soil fill having a thickness of 5 m is to be made of a soil with a Proctor maximum dry unit weight of 20 kN/m³ and an optimum moisture content of 14%. This fill will be compacted at optimum moisture content to an average relative compaction of 95%. The underlying soils in the field are shown in Figure below. Find the total consolidation settlement in the clay layers caused by full consolidation under the soil fill load. 5 m 1 m 3 m 2 m 1 m 2 m Z GWT Ce=0.3 Cr=0.12 Cc = 0.1 Cr=0.03 PROPOSED SOIL FILL COARSE SAND COARSE SAND SOFT CLAY MEDIUM SAND MEDIUM CLAY BEDROCK Ydry = 17 kN/m³ Ysat = 19 kN/m³ Ysat = 16 kN/m³ OCR = 1 Ysat = 20 kN/m³ Ysat 18 kN/m³ OCR = 2 A soil fill having a thickness of 5 m is to be made of a soil with a Proctor maximum dry unit weight of 20 kN/m³ and an optimum moisture content of 14%.
