Abstract :

The Pirtaqi dam will be constructed in 50 km eastern of Miyaneh and 45 km south-western of Khalkhal, onQezel-Oezan River in Ardebil province. For the Pirtaqi site were purposed two dam site, named 15 and 15A. Inthis paper by using multi-criteria evaluation of AHP (Analytic Hierarchy Process), the preferred dam site fordam construction had presented. For selection of best dam site have been descript 8 criteria and 26 sub criteria,then had evaluated by using Super Decision software. On the base of preferred evaluations for sub criteria thathad depended to Q, RMR, and DMR classifications, quantitative values of RQD, SPI and GSI, permeability ofbanks and bed rock, uniaxial compressive strength, deformation modulus's, stability and conditions of powerplant tunnel, major joints and faults in dam axis, excavation volume, depth of weak pyroclastic rocks andalluvium texture, the 15A dam site has higher scores of pair wise comparison matrix and has been presented forpreferred dam site
