Abstract
Tanguyeh dam, an embankment dam with a clay core, located in southeastern Iran, is the main hydraulic structure in Kerman Province. The study area, as one of the most active tectonic zones of Iran, is covered by coloured melange and pyroclastic rocks of different lithologies. In this study, we take into account the engineering geological properties of rock masses such as discontinuities, the degree of weathering, the hydraulic conductivity along the dam axis, and ancillary structures in order to determine likely problems and necessary precautions. The significance of this study lies in the complex geological conditions and existence of a heterogeneous rocky knob along the dam axis. For this purpose, field studies such as production of an engineering geological map, study of discontinuities, permeability tests of Lugeon and rock quality designations,and sampling of recovery cores for laboratory tests are implemented. Finally, the results of the field tests and engineering geological studies are investigated.
