Bolt pattern discreteness in jointed rock: dataset and analysis code

Four thousand rock wedge support cases with the analysis code that produced them, supporting a study of how bolt pattern geometry affects material demand and embodied carbon in jointed rock. One thousand geological cases were drawn by Latin hypercube sampling over joint orientation, joint strength, groundwater pressure, rock unit weight and tunnel axis orientation, and each was analysed in four excavation geometries by limit equilibrium wedge analysis in Rocscience UnWedge v5.014. For every case the lightest square bolt pattern carrying the required support force was selected analytically and converted to steel mass, resin mass and embodied carbon for an epoxy and a vinyl ester resin system. The deposit contains the full case table with a column dictionary, the sampling plan, the unmodified UnWedge result workbooks, five UnWedge model files for the verification cases, the robustness and model comparison outputs, every analysis script, and each manuscript figure as a 600 dpi raster and a vector file. A README explains the contents and how to reproduce the results. No human participants, no personal information and no field data are involved. Every value is either a computed model output or a published material property. Carbon factors and bond strengths are drawn from manufacturers' Environmental Product Declarations and published inventory data, which are identified by registration number but not redistributed here.
