Sediments are porous, with the possibility that the fluid and granular phases will vibrate differently in response to acoustic excitation. Poroelastic theory (or Biot theory) treats both porosity and elasticity. As will be seen, poroelastic effects are noticeable in sand, but are presumably less important in softer sediments where Gassmann's equations may be adequate. While this theory has had some success in application to sediments, it appears likely that a complete understanding of the acoustics of sediments may require a modification or generalization of Biot theory. Some proposed modifications are mentioned later in this chapter and in Ch. 11. [ABSTRACT FROM AUTHOR] |
