QUESTION 11 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 Cu = 50.3 kN/m2 Ysat = 17.6 kN/m 13.72 m Clay Cu = 85.1 kN/m² Ysat = 19.02 kN/m3 889 mm
