Hydrotechnical facilities during construction and operation may be subject tonon- project impacts (including non-project subsidence). At the same time, in the reinforced concrete constructions a system of cracks occurs, the nature of which corresponds to the complex features of the acting loads. On an example of the HPP (PSPP) building are encouraged to strengthen concrete structures of hydraulic system of external reinforcement on the basis of carbon fiber. Based on numerical simulations computational justification of proposed technical solutions to strengthen concrete structures of hydraulic structures is performed
