The article provides the results of computational studies of the stress-strain state of reinforced concrete structures chambers of locks No. 15 and No. 16 of the Gorodetsky complex of hydraulic structures, performed on the basis of a finite element model taking into account the data of long-term monitoring and field surveys. Combinations of loads that are pleasant in computational studies correspond to the most unfavorable operating conditions. The applied finite element models take into account the structural features of the structure, including interlocking construction joints and the actual location of the reinforcement. In the computational studies, the load-bearing capacity of the actual anchoring of the new repair concrete and the concrete of the main array was checked; the distribution of vertical stresses in the chamber walls, in the reinforcement of the chamber wall, the values of the main stresses in the concrete block under the construction joint was obtained. Conclusions are drawn about the values of horizontal displacements of the upper parts of the chamber walls, cracking in the walls, and the need for reliable anchoring of new repair concrete to the concrete of the main array.
