| 摘 要： | 三峡水库蓄水后,荆江河段冲刷以枯水河槽冲刷为主,对航道条件将产生显著影响,其中窑监河段近年来航道条件持续恶化.分析不同年份监利河段洲滩形态与删除碍航程度,认为三峡蓄水后洲滩受到冲刷是航道条件恶化的原因之一;而通过对浅滩段横断面年内变化及各年汛后退水过程中水位变化与航道水深变化对应关系分析,初步确定了退水过程中最佳的冲刷...

| Abstract: | After impounding of the Three Gorges reservoir,river bed erosion in the Jingjiang reach downstream the dam is dominated by low-water scour.This can cause a significant impact on navigation conditions;in particular,the conditions of Jianli reach that keep deteriorating in recent years.In this paper,relationship between the shapes of bar and shoals and the navigation-obstructing extent in the Jianli reach is analyzed.The results show that the erosion of bars and shoals is a major factor for the worsened condi... |
