Geotechnical parameter sets
Define geotypes with unit weight, cohesion, friction angle, stiffness, overburden, and other calculation parameters.
Geotechnical calculation software
Calculate tunnel loads with confidence.
Tunnel Design supports engineers with focused geotechnical calculations for tunnel design: geotypes, groundwater effects, primary pressures, and tunnel face stability.

Built for tunnel geotechnical calculations.
Keep soil and rock parameters, groundwater assumptions, and calculation outputs transparent, repeatable, and ready for engineering review.
Primary tunnel pressures
Calculate vertical and horizontal ground pressures acting on the excavation and preliminary support.
Loads at the tunnel face
Evaluate face pressure and stability using established approaches including the Jancsecz-Steiner method.
From ground model to calculation result.
A compact workflow for technical checks, parameter control, and reproducible geotechnical outputs.
STEP 01
Input
Define tunnel geometry, overburden, excavation dimensions, and groundwater level.
STEP 02
Assign
Select geotypes and parameter sets for soil or rock layers around the tunnel.
STEP 03
Calculate
Run primary pressure and face pressure checks with transparent formulas.
STEP 04
Review
Compare variants, verify assumptions, and export calculation-ready results.
