Data and code for: Identifiability of Support Demand and Plastic Radius from Tunnel Convergence in Elastic–Perfectly Plastic Rock Masses

Version 1.0, 2026-09-29. DOI: https://doi.org/10.5281/zenodo.23040284. Licence: CC BY 4.0 (data and code). The package holds what is needed to check and reproduce the results of the article: the result files listed in Supplementary Section S2 (results/), the inputs and extracted quantities of the Abaqus analyses and the two tables of the published field case (data/), and the code of the forward models and of the consistent-set computations for Tables 1–3, Figures 2, 4 and 5 and Section 7, with the Abaqus user subroutine and its pre- and post-processing scripts (code/). reproduce.py reruns the code and compares the outputs with results/. This dataset accompanies the manuscript "Identifiability of Support Demand and Plastic Radius from Tunnel Convergence in Elastic–Perfectly Plastic Rock Masses".
