The ultimate goal of the study of jointed rock is to provide fundamental understanding of the mechanics of jointed rock, which is a crucial part of hard-rock tunnel design of the type that might be required for underground high-speed transport systems. The jointed-rock modeling material was selected to meet similitude requirements between the model and a typical field prototype rock and to ensure that it would be possible to make homogeneous, reproducible model specimens. A universal mold was designed for manufacturing specimens having different joint spacings and orientations. Strength tests were performed on the models in a triaxial cell. (Author)
