1. (a) List and describe the 3 different ways that piles resist loading. Use sketches to illustrate your answers. (5) (b) Consider a concrete pile that is 0.305 m x 0.305 m in cross section driven in sand. The pile is 15 m long. Shown below is the variations of Standard Penetration Test values with depth and the Soil Profile. Estimate the ultimate bearing capacity using Meyerhof (1976) method. State any assumptions you make. (8) Depth SPT Value Soil Profile 1.5 8 4.5 9 7.5 14 Sand 10.5 11 13.5 20 16.5 29 Gravel 18.0 32 40ND Qb - kPa or 400N kPa whichever is the lesser B fs & NkPa Qu=Qb+Qs (c) A 500 mm diameter bored concrete pile is to be formed in the soil profile shown below. Determine the ultimate bearing capacity of the pile for embedded length of 11 m? (10) Granular fill (0-3 m) y= 20 kN/m³, $ = 30°, K3 = 1.0 Dense gravel (3-7 m) y= 21 kN/m³, $ = 35°, Ks = 2.0 Glacial clay (7-11 m) y = 20 kN/m³, Co at 7 m = 120 kPa, Ca at 11 m = 220 kPa, a = 0.6, Nc = 9.0 The following formulas should be used. a = As.Ks:/z.tan(0.754') a = axCuxAs a = coxNoxAb
