Use the Schmertman method to solve for Total settlement (S₂) of a foundation bearing on a sand deposit as profiled below with a soil unit weight, y = 120 pcf. Analyze for conditions extending to a depth 2B below foundation level. Assume E, = 9N and C₂ = 1. The groundwater table for the area of analysis is provided below. 4 ft q=3,500 psf 3 ft SOIL LAYER I 2 ft N₂-30 SOIL LAYER 2 2 ft N₁-27 SOIL LAYER 3 2 ft N₂-31 2ft SOIL LAYER 4 Question 1 From the Schmertman diagram provided, determine the net foundation pressure (delta Q) O 3260 O 3290 3270 O 3250 Question 2 5₁ From the Schmertman diagram provided, determine the vertical pressure below the foundation (Sigma vp) Ⓒ 450 Ⓒ 580 O 480 Ⓒ 490 Question 3 5 pts From the Schmertman diagram provided, determine the Maximum Strain Influence Factor (vp) 0.750 0.761 0.780 0790 Question 4 From the Schmertman diagram provided, determine C1 Factor (C1) 0.945 0.960 O 156 O 125 5 pts 5₁
