Abstract

Abstract: For water conservancy projects that have been built on rivers with high sediment concentration, the sediment deposition is the primary problem affecting safe operation. Based on a large hydropower station already built on the Yellow River, combined with model test, simulation analysis and other methods, this paper proposes that the effective method to solve the sediment problem is to use the newly built desilting tunnel to arrange the water diversion power generation system, and give the measures to solve the siltation of power generation hole and surge chamber involved in this method. The engineering practice shows that the siltation prevention and reduction measures mentioned in this paper can effectively solve the siltation problem of the old hydropower station in the high sediment content reservoir area.
