Abstract
At present the results of a visual inventory of most of the water bearing structures in Russia is in a state that requires a major overhaul. Practice shows that, after this period of time, facilities continue to operate without being replaced by new ones, and sometimes even without a thorough reconstruction, to restore and reconstruct the existing structures on the basis of emerging new and previously used reliable technology. The object of the study was considered Tashla underwater pipeline right-Yegorlykskaya channel. In the numerical formulation of mathematical experiment task was to scientifically determine the reliability of structures for such a long life (50 years), with different types of defects and damage. All calculations were performed on a certain software product SolidWorks, which is based on the method of finite elements and superelements.
Keywords: hydraulic structures, water-conducting channels, inverted siphons, non-destructive inspection methods, modeling, technical condition.
