Computer Applications in Geotechnical Engineering (CAGE) and Geotechnical aspects of the Computer-Aided Structural Engineering (G-CASE) projects. User's guide. UTEXAS2 slope-stability package. Volume 1: User's manual

This report is the user's guide volume of the UTEXAS2 (University of Texas Analysis of Slopes - version 2) slope-stability package. This package describes a slope-stability program which can calculate the factor of safety by Spencer's method, simplified Bishop's procedure, force equilibrium procedure with Corps of Engineers Modified Swedish side-force assumption of parallel side forces at a user-specified inclination and force equilibrium procedure with Lowe and Karafiath's side force assumptions. The program will calculate the safety factor for either a prescribed shear surface or for a search of the critical shear surface. Both circular and noncircular shear surfaces can be evaluated. There are five options for the type of shear strength data and six options for specifying pore pressures. All analysis procedures and major features can be run in a single data file which is free-field format and utilizes command words. Graphics capability for displaying the input data and the final shear surface is available. Special capabilities include pseudo-static seismic analysis, slope reinforcement, curved (multi-linear) shear strength envelope, anisotropic shear strength, and the ability to have multiple piezometric lines.
