Stress-strain state of variant of rockfill dam with conrete facing of Kambarata-1 hydropower plant

The 2-D stress-strain state analyses of Kambarata and TSQ-1concrete face rockfill dams were performed using ADINA program with ideally elasto-plastic model of rockfill with Mohr-Column criterion. The great influence of consequence of construction on the stress-strain state of both dams was received. The new effective method of decrease of deflection of concrete face by roller compacted concrete (RCC) elements integrated under the middle of concrete face was proposed and assessed for Kambarata dam. The proposed Kambarata concrete face rockfill dam is the most favorable one comparing with the traditional concrete of rockfill dams whose are under design now.
