Studies on hydraulic characteristics of the inverted siphon crossing yellow river in diversion works from south to north in China

摘要

Using model tests, this paper studies hydraulic characteristics in the inverted siphon crossing Yollow River, including the discharge capacity flowing inverted siphon tunnel and lateral overflow weir at regulation sluice of tunnel exit, the pattern in intake and exit of tunnel, the downstream energy dissipation and anti-erosion of tunnel exit and the dispatch method for safe operation of tunnel and main channel. Testing results show that these hydraulic characteristics are satisfied for designing requirement.
