Abstract : This report is the user's guide volume of the UTEXAS3 (University of Texas Analysis of Slopes - version 3) 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 seven 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 two-stage and three-stage stability computations to simulate undrained loading following a period of soil consolidation, external concentrated forces, internal slope reinforcement, curved (multi-linear) shear strength envelope, anisotrophic shear strength, and the ability to have multiple piezometric lines. Six conceptual examples are included to illustrate data input procedures and computations analyses.
