WORLD EXPERIENCE IN THE CONSTRUCTION OF GRAVITY DAMS FROM A PARTICULARLY LEAN CONCRETE MIX

Abstract

The article discusses the main aspects of the construction of dams with a symmetrical profile from the mate-rial "solid embankment" or other names ("lean" concrete, cemented "sand and gravel mixture" CSG). The design of typical profiles of dams of implemented projects is considered, and information regarding the characteristics and methods of production of this material is provided. The main properties of this material and the principle of its preparation are considered. The work in this area of engineers from Russia, Japan, Iran, Korea, China, and Turkey is analyzed. These dam structures are characterized by high reliability and efficiency, but also, most importantly, by a much higher adaptability or high speed of construction, which is little dependent on local natural factors than traditional rolled concrete dams.
