Parametric Model of Tunnel Number 01

Tunnel Number 01

  • Parametric Model

Design Challenge

Tunnel construction involves a trade-off between cost and structural stability. Engineers must optimize material selection, excavation methods, and design parameters to ensure a durable, cost-effective tunnel. Conventional methods lack flexibility in evaluating multiple design alternatives quickly.

Solution

Our parametric tunnel model, developed in Dynamo, provides a dynamic approach to tunnel design. By integrating cost and stability parameters, the model allows users to explore different excavation techniques, materials, and geometric configurations to identify the most efficient solution.

Design Alternatives

The model considers multiple design scenarios, such as:

  1. Reinforced Concrete vs. Steel Lining for structural durability.
  2. TBM (Tunnel Boring Machine) vs. Drill & Blast excavation techniques.
  3. Circular vs. Horseshoe Cross-Section for stability and space optimization.

Each alternative is assessed based on cost, construction time, and stability scores.

Conclusion

This parametric model enhances decision-making by providing real-time cost and stability analysis, reducing the time required for feasibility studies. By integrating flexible parameters, engineers can optimize tunnel designs for varied geological and economic conditions.
