Abstract
The under construction eyvashan dam site in Lorestan Province is located in 57 km Northeast of the Khorramabad city on Hored River. The site of this dam, from geological point of view is in bedrock ranging that is composed of conglomerate rocks. Conglomerate rocks of abutments range have protrusions. Young alluvial deposits covered the bedrock surface in valley floor. The aim of this study is to investigate the geological parameters of eyvashan dam site and the reasons for choosing the best type of dam building and also the stability of the structure in order of size motechnique. The study method has done based on research, data collection in library studies, field and laboratory ways. After identification and evaluation of geological and geotechnical of dam structure, litho logy and tectonic characteristics were studied by using satellite data. In choosing the type of dam issues and several factors such as the shape of the valley, engineering geological conditions and results of exploration drilling and geotechnical studies, site conditions, the situation tectonics and seismicity, appropriate credit sources and barrier height are ruling. According to the above-mentioned conditions and by summarizing information and impartial obtained investigations, construction of dam earthen gravel type with clay core is the best option. Also the analysis of liquids and permeability and its fulcrum in order to design appropriate sealing curtains were detected.
