Abstract:

A geomechanical model study was conducted with the objective of adding to the present knowledge of the strength, behavior, and failure of a jointed rock mass. No specific prototype is simulated by this study. The program of study consists of five phases the development of a rock-like model material the design and construction of the loading apparatus the development of a complete instrumentation system the testing of jointed and unjointed models and the analysis, interpretation, and presentation of the test data. The rock-like model material developed for use in the model tests has characteristics of rock in general and a schistose gneiss rock in particular. It is a high density, low void ratio material obtained by vibrating a sand-gypsum cement-water mix on a vibrating table. Measurements taken and recorded for each test are the applied pressures and the resulting strains and displacements in jointed or unjointed models. Author
