摘要：
The properties of the face zone material as a flexible foundation of the face play an extremely important role in the formation of stress-strain state of rockfill dams with reinforced concrete face. Stone-concrete, made by watering the stone backfill with cement-sand mix containing water-reducing agents is proposed to be used as such foundation in the paper. Methods of selecting the composition of the casting mixture and search results of its optimal composition by the method of factor analysis are given in this paper. The properties of stone-concrete are investigated and a dam design technique is developed based on the selection of optimal properties for the face zone of that material.
