Assessment of hydrodynamic loads on the slabs of the culvert fastening of reclamation waterworks

The results of experimental studies of the distribution of averaged and pulsating loads on the fastening slabs of an expanding culvert and apron, measured using point sensors and total load sensors in the presence of three rows of flow energy absorbers at the bottom behind a short-span tubular spillway, are presented. Considerations are presented on the use of the obtained data to clarify the hydraulic and hydraulic engineering calculations of three-point culvert structures during their design, repair and renovation. The change in average pressure differences, pressure pulsation standards, total hydrodynamic load and amplitude-frequency characteristics of the flow on the fastening downstream elements of the Shamkir hydroelectric complex for reclamation purposes, reconstructed on the Kura River in Azerbaijan, has been studied. It has been established that to ensure the reliability of spillway structures, the determination of total loads and the construction of a quasi-static loading of the downstream fastening, the choice of its rational design and the optimization of operating mode scan be carried out, together with the use of known recommendations and objectively developed scientific methodology, making adjustments based on the results of model studies.
