麻石船闸改扩建工程下引航道优化布置数值模拟
|
摘要
融江麻石船闸改扩建工程下引航道位于右岸,规划航线偏向河心,下泄洪水斜冲引航道,造成口门区通航条件十分复杂。采取规划航线向右岸侧偏移、布置隔流堤、增加导流墩和改变导流墩轴向角等措施提出3个优化布置方案。建立麻石枢纽下游河道的整体二维水流模型开展仿真模拟,分析比较各个优化方案的口门区的通航水流条件,得出满足通航安全指标的最优布置方案。
The lower lock approach of Mashi lock extension project is located on the right bank of Rongjiang River and bent to main flow,flood thrust obliquely channel so that the navigation condition in the entrance area is very complex.We put forward three optimized layout schemes by these measures,such as planning the deviation of the route to the right bank,arranging the breakwater,increasing the diversion pier and rotating the axial angle of the diversion pier.Using numerical simulation of whole two-dimensional flow model of Mashi hydro-junction,we analyze and compare navigation flow condition in entrance area of every optimized layout schemes,and obtained the better scheme which can meet all navigation safety index.
