SOME PROBLEMS OF DURABILITY AND RELIABILITY OF HYDRAULIC ENGINEERING STRUCTURES

Reliability and durability of hydraulic engineering constructions is considered. The durability is estimated by duration of their non-failure operation in the given operational conditions from the moment of erection before full loss of operational properties. Rational it is necessary to consider such design in which basic elements and units of interfaces have about an identical degree of durability. The estimation of a degree of risk at failures on hydraulic engineering constructions is connected with a problem of forecasting of parameters of reliability and a residual resource of functioning system. One of the basic parameters of reliability of object is the probability of absence of emergencies on some time interval of time.
