I attempted to simulate a tunnel with a joint using tiebacks. However, I observed that the tiebacks did not significantly impact the stress and displacement within the tunnel. I am seeking your advice on how to properly align the tiebacks and what parameters should be used to optimize their effectiveness.

Attached is the script detailing how I conducted the simulation. I would greatly appreciate any recommendations or insights you can provide.

Thank you for your guidance.
