Wave Transmission through Rock Structures. Hydraulic Model Investigation.
Abstract
Application of the energy method leads to a theoretical expression of the coefficient of transmission through a prismatic structure, constructed from rocks of uniform size, for long waves traversing the structure. When the dissipation in the voids is due partly to turbulent forces, the transmissions are expressed by a power formula. The formula is modified by a parametric factor to respond to the conditions met with in the ordinary model studies of the shorter waves. The factor form is determined from observations made with waves of varying periods. The relation of the adapted formula to the resistance of the structures for steady flow is shown. With the reflections not being amenable to an analytical treatment, test results are consolidated in a single curve, irrespective of the rock sizes, with the porosity remaining constant. (Author)
