RS3 across Applications

Design and analyze tunnel excavations and support systems with features like multi-stage analysis, 3D simulation of support installation and the 3D tunnel designer.

Geotextiles, shotcrete, reinforced concrete liners and various bolt types make up the extensive library of options for modelling supports of slopes, retaining walls, excavations and other geotechnical structures.

Capable of analyzing any surface or underground excavation including staging and support installation for civil, mining, tunneling and other geotechnical applications.

Used in both open pit and underground mines, analyze slope stability and design benches and underground caverns and opening with efficiency.

Advanced slope stability, groundwater seepage, consolidation and dynamic analysis tools are built for efficient modelling of earth dams.

Explore the latest features in RS3

Easily define the liner local coordinate system using the tunnel direction and side faces. Effortlessly follow the tunnel shape, and direction, and define the tunnel frame to seamlessly plan an effective excavation.

Conveniently import your RS2 projects into RS3 using the new RS2 Import Wizard. This feature helps define the extrusion width of the model, applies restraints for the extruded model, and automatically generates mesh for your model as you import.

This powerful tool is used for defining any tunnel profile and generating sequence-based tunnel models. Easily define tunnel models in various shapes, add supports, and specify excavation stages. Accelerate and advance the tunnel modeling process with RS3’s Tunnel Designer.
