terzaghi_1d
(z, t, H=1, kv=1, mv=0.1, gamw=10, ui=1, nterms=100)[source]¶ 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’
