Tunneling
& Excavation
Explore advanced tools for designing, staging, and supporting safe underground and surface excavations.
Enabling engineers to analyze stress, deformation, and stability for tunnels, caverns, shafts, and excavations.
From early alignment and support concepts to detailed staged construction models, our tools bring numerical analysis and practical design workflows together so engineers can manage ground response and support performance with confidence.
Built for Tunnelling and Excavation Insight
Model complex sequences for tunnels and excavations in RS2 and RS3, including advance‑and‑support stages, support installation, and construction phasing to capture realistic ground–structure interaction.
Use RS2 and RS3 to evaluate stress redistribution, deformation, and potential failure around underground openings and surface cuts in both soil and rock.
Assess structurally controlled failure in excavations with UnWedge and RocTunnel3 to size and position support for challenging jointed rock masses.
Incorporate groundwater pressures, seepage, and drawdown into tunnel and excavation models in RS2 and RS3 to understand their impact on stability and support demand.
Calibrate material properties in RSData from lab and field data, reuse them across RS2, RS3, UnWedge, and RocTunnel3, and visualize results with clear plots, sections, and 3D views for design reviews and communication.
