冲积河流整治水位与整治线宽度关系研究

Research on the relationship between regulation water level and regulation width of alluvial river

整治水位与整治线宽度是一个有机的整体,两者之间相互影响、相互制约。根据拟整治浅滩"冲刷总量相同"原则,基于泥沙运动学和河床演变学原理,综合研究整治水位和整治线宽度,推导得出两者之间的关系公式,并利用已有资料进行了验证。在此基础上,就公式应用进行了初步探讨。结果表明,在浅滩整治效果相同的前提下,可以选取多种不同整治参数组合。

The regulation water level is closely related with the regulation width and should be treated as a whole. The twoinfluence each other and restrict each other. Under the assumption of the same scouring amount for a given shoal, we derived aformula including both regulation water level and width by applying sediment transport theory and riverbed evolution theory,and verified it by using existing data. Furthermore, we discussed the application of formula. The results show that thecombination of different regulation parameters can be selected under the premise of the same effect of shoal regulation.
