Please help me if volume loss has to consider in NATM tunnel. If yes, will it be same as TBM tunnel or has to consider on higher side.

NATM multidrift model sigma Mstage

Sumit Wagh — Tue, 11 Jul 2023 11:49:44 GMT

When I excavate the highlighted mass in the following image, the model fails to analyse the data. Some one suggested to reduce the sigmaM stage parameter to 0.3. in that case model is working. however getting warning massage mentioned as "Prescribed ultimate state fully reached. Unfinished construction stage. Next calculation must be staged construction. [Warning code: 2]" Hence i feel its not correct to reduce sigma M stage. some one please help with the modeling approach.
