What does this research mean for the field?

The Hardening Soil (HS) constitutive model and the Peck (1969) empirical method provide more accurate and consistent predictions of tunnelling-induced surface settlements than the Mohr-Coulomb (MC) model, with the HS model achieving up to 95% accuracy against measured field data. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?
