shaft.nordlund_k_delta()

Nordlund lateral coefficient for a non-tapered displacement pile.

Usage

Source

shaft.nordlund_k_delta(
    phi,
    displaced_volume,
)

Parameters

phi: array_like

Friction angle, deg.

displaced_volume: float

Soil volume displaced per unit length, m^3/m.

Returns

ndarray

K_delta, interpolated in log10 of the displaced volume and log-linearly in friction angle; the 35 to 40 deg slope is continued above 40 deg.
