Notes / Remarks

Pile▼

Length (m)

Diameter (m)

Pile Type NOTE: Pile length must be less than the total soil depth.

Groundwater▼

Consider groundwater table

Water table at (top of layer):

γ_w (kN/m³)

Soil Layers (top → bottom)▼

Code Provisions▼

Primary method

α (cohesive)

β (sand)

Use m = 0.8 (silty soils) for β calculation. Otherwise m = 0.6

⚙️ Note: Entered α or β values override the automatic AASHTO-based calculations.

Nc (end bearing)

φ_tip (0–1)

φ_{shaft, clay} (0–1)

φ_{shaft, sand} (0–1)

User Options▼

Show calculations in layers Ignore shaft friction at top (m) Ignore shaft friction at bottom (m) Max effective stress depth (×D) Applied load, Q_applied (kN)

End Bearing Parameters

N₆₀
N_q (override):
For sand tip: if N_q is given, program uses N_q × σ′_v; otherwise it uses N₆₀-based Reese & O’Neill (1988).
