TerraWiz STABL WV 2008 is a state-of-the-art Windows-based slope stability software that retains all the traditional features of stabl that the geotechnical community has come to value over the almost 30 years of experience with STABL and PCSTABL algorithms but has all the advantages of state-of-the-art geotechnical software. Users can still open and save the traditional text input files (with the advantage that old input files are error-checked upon opening) and perform Bishop, Janbu and Spencer analyses of slopes. Besides tiebacks, nails and geogrids, stabilization using piles can also be analyzed. Additionally, the powerful data-processing, visualization and reporting tools of STABL WV 2008 lead to time savings and confidence in the results of each analysis.
