摘要
在总结分析现有整治线宽度确定模式的基础上,根据长江中下游碍航浅滩冲淤特点及不同类型浅滩整治前后断面输沙关系,提出了适应不同类型浅滩整治的局部输沙模式及平衡系数确定公式,建立了能够适用于束窄河宽和调整断面水沙分配等不同形式建筑物整治线宽度确定的统一公式。
Based on the summarization and analyses of the existing modes of the regulation width, the shoal evolution characteristic, and the relationship of sediment transport between the pre- and post-rgeulation of the shoals in the middle and lower reaches of the Yzngtze River, the local sediment transport mode for the different types of shoals and the formula of the equilibrium coefficient are established. In addition, the unified formula to compute the regulation width of different types of channel training work is developed.
