Infinite Slope v3.0
Software for slope stability analysis based on the limit equilibrium analysis of the well known 'infinite slope' model. The visual intuitive approach enriches the analysis experience both for educational and for professional purposes.
US Radar Inc
US Radar is a technological leader and manufacturer in the design and innovation of surface and ground penetrating radar (GPR) systems and software. If you need to see what is on the other side of a surface, their high-profile GPR, Utility Mapping, and GIS software technologies will accurately help you define what can't be seen with the bare eye.
A powerful and easy to use ultimate limit state geotechnical analysis software program which is FREE to universities for teaching and research use. The software effectively bridges the gap between hand-type analysis methods and significantly more complex tools (e.g. based on finite elements). The software is a flexible tool for use in teaching (see http://www.geotech.shef.ac.uk/trac/wiki/TeachingResources) and provides rigorous plasticity solutions for use in research.

is a selection of software for beam on elastic foundations, sheet piles,
axial piles, & lateral piles available for free from Delft University

Federal Highway Administration
The Federal Highway Administration (FHWA) has free downloadable software
including SPILE (vertical pile capacity), EMBANK (settlement of embankments),
CBEAR (bearing capacity of shallow foundations), COM624 (lateral pile
spring model), and others located at:
The Delft Geotechnical Lab has written an extensive FEM
program called Plaxis which is quite powerful but costs around US $4000.
An intro version is about $750 US.
