TSLOPE — next-generation slope stability software
Used for all types of slope stability problems including open pit mines, landfills, and any slope with complex geological structure and variable surface topography. Built as a fully 3D application with vertical-column discretization. Set up 3D models in minutes. Import CAD, geology, and terrain data. Cut 2D sections from 3D or extrude 2D to 3D. Apply pore pressures at the failure surface with automatic tension cut-off. Compute local factors of safety at each column base.
