For a sand drain project the following are given: Clay: Normally consolidated H. = 5.5 m (one-way drainage) C = 0.3 e, = 0.76 C, = 0.015 m/day Effective overburden pressure at the middle of clay layer = 80 kN/m? Sand drain: r= 0.07 m de = 2.5 m Cy = Cyr A surcharge is applied as shown in Figure P5.13. Calculate the degree of consolidation and the consolidation settlement 50 days after the beginning of the surcharge application. Surcharge (kN/m?) 70 →Time (days) 30 FIGURE P.5.13
