5. Based on one-dimensional consolidation test results on a clay, the coefficient of consolidation for a given pressure range was obtained as 9x 10-3 mm²/s. In the field, there is a 4 m-thick layer of the same clay with one-way drainage. Based on the assumption that a uniform surcharge of 90 kN/m2 was to be applied instantaneously, the total consolidation settlement was estimated to be 160 mm. However, during the construction, the loading was gradual; the resulting surcharge can be approximated as Estimate the settlement at (a) t-45 day and (b) 150 days. kN 90 a(m²) = 90t kN 9 (m²) = 90 for t ≤90 days for t > 90 days
