WebFeb 28, 2024 · Table 1: Interpolated values of N q (Meyerhof’s theory) Clay Soil. Equation 4 can also calculate the end-bearing capacity of piles in clay or cohesive soils (φ ≈ 0). Since soil friction angle is neglected and the bearing capacity factor (N c) has a constant value of 9 for cohesive soils, Eq.4 can be written as:
