摘　　要：碍航特性分析对于枢纽上游水位变动区的急弯航道设计尤为关键。针对浯溪枢纽上游马头岭急弯复杂的水流条件,采用平面二维水流数学模型与船模相结合的技术手段,进行不同水位组合下弯道河流碍航特性研究,在分析航道水深、航道流速的基础上提出优化方案。结果表明,枢纽上游水位变动区的通航设计水位受枢纽运行调度方案的影响较大,急弯航道航线调整是优化通航条件的有效思路,可为类似项目建设提供借鉴。Analyzing navigation-obstructing characteristics is particularly critical for the design of a sharp bend channel in a water-level-fluctuating zone upstream from a hydro-junction.Considering the complicated water flow conditions of the Matouling sharp bend upstream from the Wuxi Hydro-junction,we adopt the technical means of combining a two-dimensional planar mathematical water flow model with a ship model to study the navigation-obstructing characteristics of the bend river under different water level combinations.An optimization scheme is proposed by analyzing the channel depth and flow rate.The results show that the navigable design water level of a stage-fluctuating zone upstream from a hydro-junction is greatly affected by the operation scheduling plan of the hydro-junction.Adjusting the route on a sharp bend channel is an effective idea for optimizing navigable conditions.This research serves as a reference for the construction of similar projects.
