Calculation Methodology for Defining the Filtration Coefficient of a Rock Mass with Loose Crack Filler

Resumo

Atechnique is proposed that makes it possible to solve the problem of determining the filtration coefficient of a rock mass used as the base of hydroconstructions. The basic data for calculation are the parameters of a network of cracks in the mass and the filtration coefficient of the crack filler. In view of the anisotropy created by the network of cracks, the main characteristic of water penetration is the permeability tensor. The authors’ technique is applicable for evaluating slightly wet rock masses and is in a class by itself in determining water penetration of permafrost rock masses.
