【摘要】：以五里亭船闸下游引航道整治措施为例,建立了二维水流数学模型,对岸嘴开挖、隔流墙设置、疏浚、航线调整等措施进行研究,详细阐述了典型引航道水流条件的逐步优选过程,提出了五里亭船闸下游引航道推荐整治方案。通过对方案的逐步优选,得出:(1)引航道整治措施优选是多约束条件下的渐进过程,除论证通航可行性外应兼顾发电、行洪可行性,孤立分析通航整治措施可能给出极不合理的工程建议,而这在许多通航论证中常被忽视;(2)对于具体工程,引航道隔流墙的长度理论上存在最优值;(3)淹没式长隔流导航墙可满足掩护引航道水流条件的要求,同时也不妨碍电站出力和河道泄洪,是通航水流条件较差船闸引航道整治的有效措施。
[Abstract]:Taking the regulation measures of the downstream approach channel of Wuli Ting Lock as an example, the mathematical model of two-dimensional flow is established, and the measures such as excavation of the shore nozzle, installation of the barrier wall, dredging, route adjustment and so on are studied. In this paper, the process of selecting the flow conditions of typical approach channel is described in detail, and the recommended regulation scheme of the downstream approach channel of Wuliting Shiplock is put forward. Through the gradual optimization of the scheme, the following conclusions are drawn: (1) the optimal selection of approach channel regulation measures is a gradual process under the condition of multiple constraints. Besides proving the feasibility of navigation, the feasibility of generating electricity and flood discharge should be taken into account. Isolated analysis of navigation regulation measures may give extremely unreasonable engineering suggestions, which are often ignored in many navigational argumentation; (2) for specific projects, The length of the diversion channel wall has an optimum value in theory. (3) the submerged long barrier navigation wall can meet the requirements of the water flow conditions of the cover approach channel, and at the same time, it does not hinder the power generation of the power station and the flood discharge of the river. It is an effective measure to regulate the approach channel of the ship lock with poor navigable flow conditions.
