TSLOPE FEATURES

2D and 3D slope stability software in one workflow

TSLOPE slope stability software lets you build or import a project once, analyse it in 2D and 3D, and compare the results without rebuilding the model between separate programs. Bring in existing GIS, terrain, CAD and 2D slope models, keep the engineering assumptions visible, and move quickly from site data to a defensible factor of safety.

Full 2D and 3D analysis from US$175/day, with no annual commitment required.

What makes TSLOPE different

Use the project data you already have Transfer QGIS data or import terrain, CAD, Slide2 and SLOPE/W models instead of rebuilding everything from scratch.

Compare 2D and 3D directly Extract a 2D slope case from a 3D model or extend an existing 2D model into 3D within the same workflow.

Keep the engineering visible Review failure geometry, support forces, sliding direction, local factors of safety and other analysis behaviour.

Licence it around the project Choose Day, Week, Month or Year access with the same full feature set.

2D + 3D Analyse both in one package.

QGIS workflow Use mapped project data with less rework.

Existing models Import Slide2 and SLOPE/W projects.

Flexible licensing Day, Week, Month or Year.

PRACTICAL WORKFLOW

Move from existing project data to slope stability analysis with less rework

TSLOPE is designed around the way geotechnical projects actually develop. Start with a known 2D model, mapped GIS information, terrain data or engineer-defined geometry, then test the interpretation in both two and three dimensions.

QGIS

Keep mapped site data connected

Transfer contours, geological surfaces, boreholes, boundaries and slope data from QGIS into the TSLOPE modelling workflow.

2D TO 3D

Extend the analysis without starting again

Import an existing Slide2 or SLOPE/W project and extrude the section into 3D, or create a 2D slope case directly from a 3D model.

ENGINEERING REVIEW

See why the result changed

Inspect the assumed failure geometry, forces, sliding direction and calculated behaviour rather than treating the factor of safety as a black-box output.

PROJECT FLEXIBILITY

Pay for the access you need

Every licence includes the full 2D and 3D capability. Choose a Day, Week, Month or Year licence depending on the project.

Contractor perspective

George,
Geovert

“The ability to model the slope in 3D was particularly useful as this provided a more realistic representation of the failure geometry and helped optimise the anchor spacing to the benefit of the client.”
