NUMERICAL SOLUTION OF THE FILTRATION-DEFORMATION PROBLEM IN THE CASE OF PHASED CONSTRUCTION OF A STORAGE DAM
Main Article Content
Abstract
This paper presents the results of numerical modeling of the joint filtration-deformation problem for a storage dam taking into account its construction and filling of the pond bowl in 3 stages. Two variants of the structure operation were considered: with the tubular drainage operating and excluded from operation. According to the results of researches the stability of the structure and parameters of filtration regime were evaluated. Recommendations on ensuring reliability and safety of the structure are formulated.
