UTEXAS4

UTEXAS4 is a two-dimensional slope stability analysis program widely used in geotechnical engineering for evaluating the factor of safety of earth embankments, dams, natural slopes, and excavations. It applies established limit-equilibrium methods, supports both circular and noncircular slip surfaces, and includes automatic and user-directed searches to identify the critical failure surface. The software accommodates layered soil profiles, various ways to model pore-water pressures (such as water tables and user-defined distributions), surcharge and pseudo-static seismic loading, and provides clear visualization of potential failure surfaces along with detailed, tabulated results. Engineers use UTEXAS4 for design, assessment, and back-analysis of slopes and landslides due to its robust algorithms and practical workflow.

Key capabilities:

• Limit-equilibrium analysis for 2D slope stability
• Circular and noncircular slip surface evaluation
• Automatic and manual critical surface search routines
• Flexible pore-pressure definition options
• Support for layered soils, surcharges, and pseudo-static seismic loads
• Plots of candidate and critical surfaces with comprehensive numerical output
