"SO-Triaxial" is aimed at the evaluation of triaxial compression tests (CD, CU & UU). It has a user-friendly interface and lots of smart capabilities are implemented. Individual tabs are assigned for project information (including basic information, borings and samples) and tests. In addition to test data and corresponding calculations, software outputs are available in a variety of formats.

Note that triaxial compression tests could randomly be generated based on user-defined criteria.


General features

  • User is informed about the common ranges regarding input parameters.
  • Various templates are available for the export of software outputs.
  • Test data and corresponding calculations are presented in a separate format.
  • Blank laboratory data sheets may be used for test data input.
  • Saving files with a minimal size.

Triaxial compression test calculations

  • Sample properties are automatically calculated using various methods.
  • Various data input options.
  • Two failure criteria; maximum deviator stress and maximum effective stress obliquity.
  • Test data can be edited using either graphs or tables.
  • Presentation of test results in t-s/s' and q-p/p' spaces (MIT and Cambridge stress systems, respectively).
  • Random generation of triaxial compression tests based on user-defined criteria with the ability to define custom soil behavior.
