【摘要】：嘉陵江八字腦灘群位于鳳儀航電樞紐庫尾,由于馬回電站發(fā)電泄水口與船閘出口分散布置,導致八字腦灘段右汊槽窄水淺,左汊又極其彎曲和狹窄,不具備通航條件;同時,大石塘灘段的沙卵石江心洲將嘉陵江水分為左右兩汊,左汊較順直,但枯期水深不足,右汊彎曲半徑較小,不能滿足高等級航道建設標準。針對嘉陵江八字腦灘群河段的礙航特征,應用數(shù)學模型對兩種不同的整治方案進行水流條件以及泥沙淤積情況計算分析與比較。研究結果表明:該數(shù)學模型可較好地模擬河段水流的運動及泥沙的淤積情況;從整治效果看,方案一相對較優(yōu),泥沙回淤量較少,航槽相對穩(wěn)定,可作為該灘整治方案,供設計參考。
[Abstract]:The Bazinaotan Group of Jialing River is located at the tail of Fengyi Navigation and Power Hub. Due to the scattered arrangement of the power discharge and the shiplock outlet of the Mahui Power Station, the right branch of the Bazinao beach section has narrow water, and the left branch is extremely curved and narrow, so it does not have navigable conditions; at the same time, The water of Jialing River is divided into two branches at Shitang beach, the left branch is straight, but the depth of water in dry period is insufficient, and the radius of right branch is small, which can not meet the construction standard of high grade waterway. In view of the characteristics of obstruction of navigation in the Bazhuangnaotan reach of Jialing River, two different regulation schemes were analyzed and compared by using mathematical models. The results show that the mathematical model can well simulate the flow movement and sediment deposition in the reach of the river, and from the view of the regulation effect, the first scheme is relatively better, the amount of sediment silting is less, and the channel is relatively stable, so it can be used as the regulation scheme of the beach. For design reference.
