Welcome!
This site contains geotechnical software
that can be downloaded free of charge. The software can be used to
perform geotechnical calculations, such as slope stability analysis and
sheet pile deformation. Other software is courseware, with a basic
course on soil mechanics, exercises and tests. Each program contains
information on its functionality in the form of Help-options or Manuals.
The software is distributed on the condition that no responsibility
is accepted for eventual errors, and that no liability for damages or
losses that may be caused by the use of the programs is accepted.
Since early 2002 this
website has had more than 1000 visitors per month. As of 2012 the number of
visits per month is around 5000 visitors consuming around 30 GiB of bandwidth.
I would like to thank all users of this software for the many helpful and comments made over the past 18 years.
Kind regards,
Arnold Verruijt
Arnold Verruijt passed away peacefully in his sleep on August 4, 2022. His latter years were not always easy as he had to contend with his rapidly diminishing mental capacity.
As his family we are leaving this website online and his books available for the public. Hopefully they are still of use to the civil engineering community.
