Development of a physical modelling system for 3-C x 3-D experiments

Eric V. Gallant, Donald C. Lawton, Malcolm B. Bertram

The development of the physical modelling system in the department of Geology and Geophysics at the University of Calgary began in the spring of 1983 (Cheadle, Lawton, and Bertram, 1985). This acoustical modelling system features a water- filled tank 2m deep, 3m wide, and 4m long. A system of beams and carriages are moved by stepping motors to position the source and receiver transducers over the model. Since the summer of 1989, the CREWES Project has expanded the physical modelling laboratory to include capabilities for elastic physical modelling. This paper describes the mechanical modifications of the elastic modelling system.
