This dataset accompanies the PhD thesis "Long-term basement heave in over-consolidated clay". There are 13 zip and 7z archive files, which contain experimental and computational results from the basement heave research project.

Eight of these archive files, each prefixed "Centrifuge*", contain experimental (geotechnical centrifuge modelling) data. Each zip archive contains data from one experiment, organised into one or more folders of quantitative experimental data and the Matlab .m scripts required to process them; the data are stored in comma separated value (CSV) files, with some data duplicated in XLSX spreadsheets and Matlab .mat databases for convenience. These are complemented by XLS / XLSX workbooks that tabulate and calculate salient data and observations taken manually during experiment preparation and operation.

"Horseferry Road case study.zip" provides further details on the heave monitoring data, the site investigation data, and the calculations presented in the Horseferry Road Basement heave monitoring case study. The original data and scans are provided by the courtesy of Arup Geotechnics and Laing O'Rourke who kindly agreed to make this set of data publicly available for the benefit of industry and society.

The four 7z archive files, each prefixed "Plaxis*"， contain computational (finite element modelling) data generated using Plaxis 2D 2017-01. Among these, "Plaxis HSS constitutive parameter calibration.7z" is a series of simulations of the same consolidated undrained triaxial compression tests and oedometer swelling tests using different candidate HSS (small-strain hardening) soil constitutive model parameter sets, with the aim of calibrating the HSS model. "Plaxis DYC-04 (flexi) sensitivity analysis runs.7z" and "Plaxis DYC-05 (stiff) sensitivity analysis runs.7z" contain data from 62 simulations that attempted to match two centrifuge tests, with the aim of calibrating the model parameters in soil-structure interaction simulations. Computational simulations matching the equivalent prototypes of each centrifuge test and several additional prototypes were performed using the optimised parameters, and the data are provided in "Plaxis reported results DYC-02 to 07 and variations.7z". XLSX spreadsheets of salient results from each simulation are included in the respective 7z archive.

An additional zip archive file, "Basement heave Plaxis results spreadsheets.zip", duplicates all XLSX spreadsheets reporting salient results of the Plaxis simulations. This zip is included for the benefit of data reusers who do not have access to Plaxis or otherwise do not intend to access the raw Plaxis simulation results. The data in this zip are sufficient to reproduce all the comparisons between computational simulation and centrifuge experiment results reported in the PhD thesis.
