Terzaghi 1d consolidation

Features:

Single layer.

Vertical flow.

Instant load uniform with depth.

Soil properties constant with time.

Pore pressure vs depth.

Degree of consolidation vs time.

Parameters:

z : float or 1d array/list of float

Depth to calc pore pressure at.

t : float or 1d array/list of float

Time to calc pore degree of consolidation at.

H : float, optional

Drainage path length. Default H=1

kv : float, optional

Vertical coefficient of permeability. Default kv=1.

mv : float, optional

Volume compressibility. Default mv=0.1.

gamw : float, optional

Unit weight of water. Default gamw=10.

ui : float, optional

Initial uniform pore water pressure. Default ui = 1.

nterms : int, optional

Maximum number of series terms. Default nterms=100

Returns:

por : 2d array of float

Pore pressure at depth and time. ppress is an array of size (len(z), len(t)).

doc : 1d array of float

degree of consolidation at time `t’
