<p>Natural open joints in rocks commonly present multiscale self-affine apertures.The goal of this paper is to find a geometrical model of the complex aperture that describes at best the macroscopic properties (hydraulic conductivity, heat exchange) with the ...

In this study, dynamic response of a circular tunnel embedded in a porousmedium and subjected to a moving axisymmetric ring load is investigated. To avoid treating Biot’s dynamic equations directly, two scalar potentials and two vector potentials are introduced ...
