【 摘 要 】

The paper presents a graphical method for estimating the excess pressure in penstocks under partial hydraulic hammer. Based on the proposed method, the maximum design load under hydraulic hammer in a high-pressure penstock of the Zaramagskaya HPP-1 was determined. Strength of metal shell and crescent rib of the penstock fork was evaluated under a specific load combination typical for hydraulic hammer. Variants of the fork structure reinforcement were considered. Comparison of strength reliability was performed for the variants of steel and composite steel-concrete construction of penstock fork.
