对河口整治水位的确定进行了一些初步的分析,并基于输沙平衡原理,借助于挟沙力公式,推导了河口整治线宽度计算式。运用前述的方法和公式,给出了虎跳门河口段(横山-虎跳门口)整治水位及整治线宽度。分析了虎跳门(南门涌-虎跳门口)河段航道整治工程的整治效果,结果表明,整治工程达到了预期的效果。同时,把整治后整治线内的实际冲刷厚度与利用整治线宽度计算式反推的计算冲刷厚度进行了分析比较。综合分析表明,整治水位和整治线宽度的确定方法和公式是合理的,可以给类似河口的航道整治提供参考。
An analysis has been made on determination of regulation stage of estuarine channel. Based on sediment transport balance principle and sediment transport capacity formula, a formula for the estuarine regulation line width calculation is derived. Regulation stage and width of Hutiaomen estuary (Hengshan-Hutiaomen entrance) were get by utilizing the above-mentioned methods and formula. The analyzing result of regulation effect of Hutiaomen reach engineering (Nanmenyong-Hutiaomen entrance) reveals that the regulation engineering has achieved a good effect. In addition, an analysis is carried out between the real scour thickness and that calculated by the formula. The comprehensive analyzing result shows that the determination method and formula are reasonable, thus may serve as a reference for channel regulation of similar rive estuaries.
