The dam with two culverts on the Vyunka river has been chosen for forecasting calculations. The physical and geographical features of the research area have been explored. The information on the organization of the control system of the hydraulic structure has been studied, the mix of diagnostic indicators of the state of the hydraulic structures substantiation has been carried out. The calculated values of the coefficients of the overall the upstream and downstream slopes stability for the cases considered have exceeded the standard coefficient of stability. The criteria values of the diagnostic indicators at the project stage have been defined by analysing the calculation results with ultimate element technique using the Plaxis 2D program for filtration modes, stress-strain state, strength and stability of hydraulic structures for the main and special combinations of loads. The choice of indicators is based on assessing the possibility of monitoring their values. The influence of the type of damage and destruction of the above elements has different significance on the hydraulic structures’ safety. A predictive model of deformations of the dam base was built according to the consolidation model based on the extrapolation method. The results of the obtained model of research hydraulic stricture are given.
