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.
