For a sand drain project, the following are given: Clay: Normally consolidated (one-way drainage) H = 5.5 m C =0.3;e, = 0.76;c, = 0.015 m²/day o, = 80 kPa, at middle of clay layer Sand drains: ra =0.07 m, R=1.25 m, r, = rd, &, = Cy. A surcharge is applied as shown in the scheme below. Calculate the degree of consolidation and the consoli- dation settlement 50 days after the surcharge is first applied. Total surcharge pressure, kPa 30 days = te t. Time, days Scheme 3.33
