CALCULATED RESEARCH FOR CLARIFYING PHYSICAL AND MECHANICAL CHARACTERISTICS OF THE HYDRAULIC STRUCTURES BEDROCK FOUNDATION, MADE ON IN-SITU DATA

Abstract

Definition of the real physical and mechanical characteristics for the bedrock foundations of the hydraulic structures appears to be a crucial task. It begins to be a problem number one if the construction period is prolonged and causes deterioration of the foundation. The method of definition is suggested as clarification of the physical and mechanical characteristics for the bedrock foundations of the hydraulic structures on the basis of the numerical (finite element) modeling of the "structure-foundation" system strain-stress state, taking into account the field data studies which were made during specific construction phases. The data on the Boguchany HPP concrete dam are presented as the results of the calculated clarification of the physical and mechanical characteristics for the bedrock foundations.
