A Data-Base System for Seepage Characteristies of Intact Rocks Discontinuities and Rock Masses

摘要

Fluid flow through intack rock, discontinuities and rock mass is of great concern as it plays an important role in many engineering applications such as dam, underground storage for oil, water, nuclear waste disposals ets. Therefore, information on seepage characteristics of rock mass is necessary for assessing fluid transport and its mechanical effect. In this paper, the authors describe an integrated data-base system for seepage characteristies of intact rocks, discontinuities and rock masses. This data-base system is used to study interrelations between permeability and pore diameter, porosity, discontinuity aperture, RQD and confining pressure and to check the validity of theoretical relations.
