赣江石虎塘航电枢纽船闸引航道口门区通航水流条件试验研究

Experimental Study on Entrance Area of Lock Approach of Shihutang Navigation & Hydropower Complex on the Ganjiang River under Navigable Flow Condition

结合赣江石虎塘枢纽工程水工模型对其船闸引航道通航水流条件进行了细致研究,试验观测表明:由于赣江属于宽浅性平原河流,滩槽分布明显,水流条件顺畅,流态良好,上下游通航水流条件能够满足设计船舶的安全航行,但为了节省工程量和投资,对工程进行优化,将上下游引航道外引航墙进行适当缩短后,经水工模型试验研究发现:该优化工程措施值得在同类平原河道低闸坝枢纽船闸中借鉴。

This article studies navigable flow condition of the lock channel through hydraulic model of Shihutang Navigation Hydropower Complex on the Ganjiang River.Test observation shows that the Ganjiang River is a wide-shallow plain river with swales,favorable flow condition and flow regime.Upstream and downstream navigable flow conditions can ensure safe navigation of ships.However,in order to save work load and investment,the project is optimized by appropriately shortening the approach wall outside upstream and downstream approach channels. The hydraulic model test finds that such measure of optimization can be taken for ship lock of the complex with low gate dam on a plain river.
