Rockscience, Inc. of Toronto CA is perhaps best known (as their name implies) for their software related to rock slopes and tunneling, such as Dips, Slide, Swedge, Examine3D and others. However their latest software product, Settle3D is for settlement analysis in soils. Read on for some features and screen shots. 

The interface allows for surface loading and geometries to be drawn in three dimensions. The output looks nice with contours of settlement and 3-dimensional views of increased stress in a given layer, and plots of settlement over time.

A couple of early notes based on their product data sheet and other online information:

• The layout of the problem may be in 3D as are the computation of increase in stress at depth due to surface loads. But the but the calculation of displacements and porewater pressures is performed in one dimension.
• Stress distribution can be calculated based on Boussinesq theory or 2:1 method.
• The materials can be modeled as linearly elastic, nonlinearly elastic, Janbu, or with time-dependent (consolidation) properties.
• Accounts for primary consolidation and secondary compression
  
• Can model wick drains to speed up consolidation settlement
• Ability to evaluate staged construction and groundwater conditions
