UTEXAS3

Category	Slope stability (soil)
Platform	DOS
Status	Commercial
Description	UTEXAS3 is a slope stability analysis program. Virtually any subsurface stratigraphy, including embedded walls, tunnels and voids can be included. The slope may face to either the left or right; both left and right slope faces may be analysed in a single set of input data. Shear strengths are defined: By a cohesion and friction angle. Undrained (phi = 0) shear strengths may increase linearly with depth below a horizontal reference datum or below an irregular "profile line" defining the top surface of a stratum: Shear strengths may be anisotropic: Cohesion and friction angle may vary with the inclination of the failure plane. Cohesion and friction may be expressed in terms of either total or effective stresses: Mohr-Coulomb failure envelope may be non-linear: "Two-stage" strengths may be specified. Strength envelopes may be either linear or non-linear. Pore water pressures may be defined: Zero pore water pressures: Constant value of pore water pressure: Constant value of the pore water pressure coefficient: A piezometric line - multiple piezometric lines may be used: Interpolation of values of pore water pressure or pore water pressure coefficient from irregularly spaced (un-gridded) data points. Models almost any reinforcing with any orientation and distribution of forces along the length of the reinforcement. Reinforcement may be inclined at any angle and need not be linear. Reinforcement can provide both transverse and longitudinal resistance and provisions are incorporated for reorientation (rotation) of reinforcement forces. Computations may be performed using either circular or non-circular (general shape) shear surfaces. Automatic search procedures for locating the most critical circular or non-circular shear surface using systematic (non-random) search schemes. Multi-stage slope stability computations in which the first set of computations is performed to compute the effective consolidation stresses. The consolidation stresses are then used to compute an undrained shear strength which is used in a second set of computations for the factor of safety. An additional third stage of computations can be performed when the drained strength is less that the undrained shear strength. These analyses are appropriate for loading conditions such as rapid drawdown and pseudo-static seismic loading. Other features: Distributed surface loads - shear and normal stresses with any pattern of variation. Loads may be applied to horizontal or inclined ground surfaces to simulate bearing capacity problems: Line loads: Tension cracks: Seismic coefficients for pseudo-static analyses. The companion program GRAPHIC3 provides a screen display of both input data and solution information. It can also export HPGL and DXF graphics files.
