The section of a 3 x 4 group pile in a layered saturated clay is shown in figure below. The piles have a diameter of 356 mm. The center-to-center spacing, s, of the piles is 889 mm. Note that the groundwater table coincides with the ground surface. What is the group efficiency? G.W.T. 4.57 m Clay 4 = 50.3 kN/m2 Y = 17.6 kN/m3 13.72 m Clay C = 85.1 kN/m Y = 19.02 kN/m 889 mm n= 1 - 0 (n-1)m + (m-1)n 90mn O A. 0.66 OB. 0.8 OC.0.6 O D.0.71
