By hydraulic modeling , this paper describes studies on the stability of a floating bulkhead operating in standing water and flowing water , and it ' s hydrodynamic stability characteristics that distinguish in standing water from in flowing water ; and direct measurements of the forces acting on the model floating body during floating and sinking is taken . as a result , the rotation stress curves are produced and analyzed ; to provide data for optimum operation schedule analyses of the sluice , the relationship of the impact forces acting on the side wall of the gate and the running speed is studied ; the reasons of unstably uplifting of the bulkhead are discussed and the method to solve the problem is also given in this paper 本文結合常州新閘防洪控制工程水工模型試驗,系統(tǒng)分析了浮箱門在靜水和動水中的穩(wěn)定性及其影響因素,指出靜水穩(wěn)性和動水穩(wěn)性的不同特點;試驗測定了浮箱門動水運行時的受力情況,給出并分析了定位過程轉動力的變化過程曲線;根據(jù)浮箱門啟閉速度與門體和岸墻之間撞擊力大小的關系,選擇合理的動力設備,為設計和工程實踐提供可靠依據(jù);分析浮箱門難以穩(wěn)定上浮的原因,并給出解決方案。
