METHODICAL PECULIARITIES OF PROGNOSTIC MATHEMATICAL MODELLING FOR DEFORMATION SURVEY OF HIGH DAMS
The compulsory condition of diagnostic control of dams is the creation of prognostic mathematical models in accordance with the accepted "methodology of safety criteria determination of hydraulic engineering structures" [1] and recommendations of federal law. With the development and evolution of numerical survey methods and calculating means there appeared the opportunity to survey the condition of structures on the new more detailed level. The created models of tense deformation condition of hydraulic structures due to actual loads: hydrostatic pressure, temperature, seepage condition etc. describe in details the condition of structures from field studies data. However one should be careful to use them to predict deformations. Modern Hydro Power Stations are the biggest structures on the planet, and their impact on the nature and the nearest landscape is most significant. When creating mathematical models for deformation survey of hydraulic engineering structures it is necessary to choose correctly the right form and method of mathematical description of the process being studied, to determine the necessary extent and accuracy of survey, to work out careful prognostic method and the efficiency of final results. The article describes methodical peculiarities of prognostic models’ creation for high dam deformation survey.
