ABSTRACT: The fluid flow in rock
fractures during shear processes has been an important issue in rock mechanics.
During shearing, because of the stiffer rock matrix, most deformation occurs in
the joints, in the form of normal and shear displacement. Since the joints are
rough, deformations will also change the joint aperture and fluid flow. In this
article, the hydraulic apertures of the joints of dolomitic limestone
foundation of Behesht Abad dam are investigated. Firstly, geological data
during a site investigation phase in dam site is gathered, and then related
calculations are done and the hydraulic conductivity of the joints is
evaluated. The results indicate that the hydraulic conductivity of the joints
is reasonable.
