End bearing resistance
WebSep 30, 2013 · In the Vander Veen’s method (1951), the ultimate end bearing-resistance of a pile is taken, as being equal to the point resistance of the cone. In this method, the average cone resistance over a depth equal to three times the diameter of the pile above the pile point level and one pile diameter below point level is taken as shown in Fig.1. WebDec 7, 2024 · Step 1: Compute the end-bearing load capacity (Q p ). At the tip of the pile: A p = (π/4) × D 2 = (π/4) × 0.406 2 Ap = 0.129 m2 c = 100 kPa N c = 9 (Typical value for clay) Q p = (c × N c) × A p = (100 kPa × 9) …
