A surcharge of 100 kPa is applied over a large area above the soil profile shown in the figure below. The water table is located at the ground surface. Calculate the settlement developed at the surface in mm when primary consolidation settlement is completed (acceptable tolerance = 2%). Use a single clay layer in your calculations

Two identically clay samples of the same size designated as A and B are subjected to consolidation under identical conditions. Drainage takes place through one face in sample A and through both the faces in sample B. 50% consolidation of sample A occurs in 10 minutes. The time required for 50 % consolidation to occur in sample B in minutes will be. (a) 40 (c) 5 (b) 10 (d) 2.5

Refer to Figure 2, estimate the primary consolidation settlement in the clay layer. Given: Ag = 85 kN/m²; Hi = 2 m; H2 = 4 m; and H3= 6 m. Soil characteristics are as follows: Sand: ydx 14 kN/m³, Ysat 18 kN/m³ Clay: LL = 54; e = 0.98; Ysat 19 kN/m'; Cs =- Cc 150 kN/m? H3 Sand Clay ョ→

Diaz (1992) reported the following values for Mexico City clay: void ratio (e) =12.2, natural water content (w) = 460%, and specific gravity of solids (Gs) = 2.65. Pleasedo the following:• From the given values, and assuming Vs = 1 m³, compute all of the remainingquantities entering a phase diagram, i.e., Va, Vw, Ww, and Ws.• Next, compute the degree of saturation (S).• Finally, compute the moist unit weight (γ), dry unit weight (γd), and the unitweight of the solid phase (γs)
