Directions of improvement of massive hydraulic retaining structures

Abstract

The article deals with the issues of improving hydraulic retain-ing structures of the gravity (massive) type. In order to reduce the cost of building gravity (massive) dams and increase their efficiency, a constant search for new, more efficient design solutions is underway. The purpose of the research is to analyze the main directions of improving hydraulic re-taining structures of gravity type. The article suggests a more effective method for improving concrete gravity dams, based on the idealization of structural and technological solutions. Its peculiarity is that on the basis of the identified solutions of the traditional method, an effective design of a concrete dam and the technology of its construction are selected, and then promising, patentable solutions are developed, which in their properties approach the ideal structures. In accordance with the method, the structural and technological solutions of the gravity dam with the use of coarse-pored concrete were developed. The design is high-tech and allows cooling of the dam mass by filtering water through large pores of concrete.
