Research on the Energy Dissipation Type of the Naan Reservoir in the Heishui River Irrigation District of Guangxi
摘要
Abstract
The Na'an Reservoir in the Heishui River Irrigation District of Guangxi serves the purposes including flood discharge,sediment evacuation,irrigation,power generation,and the release of ecological base flow.The buildings layout are compact.The riverbed at the dam site is a gently inclined layered rock mass with well developed mud film between the layers,which is unfavorable for the stability of the dam.When calculating the stability of the dam,the resistance of the downstream rock mass of the dam foundation needs to be considered.Moreover,the riverbed is narrow,and there is a power station arranged downstream,which imposes higher requirements for the impact of discharge atomization.The key point of the reasearch is to select an energy dissipation structure type that can not only meet the requirements of energy dissipation and erosion prevention,but also minimize the atomization impact to the greatest extent,and have a lower engineering investment.By comprehensively comparing the energy dissipation by trajectory jet and energy dissipation by hydraulic jump,and making comparisons in terms of engineering layout,protection treatment,atomization impact,and engineering cost,and combining with the verification of hydraulic model tests,the energy dissipation by hydraulic jump is recommended.关键词
