GEOSTASE®
Slope Stability Analysis Software
Version 4.30.32 (Released October 2023)
GEOSTASE® is a 2-D and 3D limit equilibrium slope stability analysis software program developed by Dr. Garry H. Gregory, Ph.D., P.E., S.E., BC.GE, Principal Consultant with GREGORY GEOTECHNICAL (GREGEO). The name GEOSTASE® is an acronym for General Equilibrium Options for STability Analysis of Slopes and Embankments. The name is a United States Registered Trademark (Registration No. 4,000,187) owned by Dr. Gregory. The program was written in Visual Fortran (double precision) using the Fortran 95 and later language versions. The program was developed for the Microsoft Windows® operating system and explicitly accommodates either English or SI units. GEOSTASE® version 4.30.32 is a 64 bit program and is compatible with Windows 7, 8, 10, and 11. GEOSTASE was originally released in January 2018. Dr. Gregory has been using the program on all his slope stability analyses for more than 10 years prior to the initial release, involving hundreds of complex analyses.
