Abstract
The research was carried out to determine the operating conditions of the downstream fastenings behind the expanding stilling basin of the mine-tower spillway of the «16 Tishrin» hydroelectric complex in the Syrian Arab Republic. Calculations were made of permissible velocities that do not cause erosion, based on the average diameters of downstream soil particles and actual velocities measured in the laboratory on a fragmentary model of the fastening unit for the outlet section of a three-point closed spillway with a shaft inlet head at maximum operating flow and operation of the structure along the entire front. The problem of deformations and erosion in the downstream of the 16 Tishrin hydroelectric complex has already existed for many years, and no practical solution has yet been found, except that every two – three years the erosion pit is filled with soil with unstudied fraction sizes. Also, during the experiments, the operation of the stilling basin was assessed under different gate maneuvering schemes. Laboratory confirmation of the proposed practical solution to this problem, ensuring reliable and safe operation of the spillway structure and the entire dam as a whole, emphasizes the relevance of solving this problem for the water economy of the northwestern part of Syria.
