Multilayer vertical and radial soil consolidation using the spectral method (one dimensional equal strain eta method)
Features:
- Multiple soil layers
- Soil properties vary linearly within a layer (permeability, compressibility, lumped radial drainage parameter)
- Surcharge load varies piecewise linear with time. Surcharge varies linearly within a layer, ratio between layers is constant with time.accept2dyear
- Pervious top, impervious bottom OR Pervious top, pervious bottom
- Top and bottom boundary pore pressure varies piecewise linear with time
- Output is pore pressure at a particular depth, average pore pressure between two points, settlement between two points (calculated using mv)
