Groundwater Conditions and Permeability

  • Walter Wittke

Abstract

A conceptual model for the permeability of a jointed rock mass was developed in Chapter 5. was found that the permeability of a rock mass is in most cases determined by its discontinuities and is anisotropic. The seepage flow in a rock mass was also shown to be steady and approximately laminar in most rock engineering problems. Consequently, problems in which the discontinuities are spaced closely with respect to the engineering structure’s dimensions may be solved on the basis of the generalized Darcy’s Law. Chapters 9 and 10 described methods of analysis capable of handling the most important seepage flow problems in jointed rock. Finally, the considerable influence of forces transmitted to the rock mass by seepage water on the deformation and stability of dam foundations and abutments has been demonstrated by way of examples (Chapter 14).
