| 摘 要： | 金钟碛为长江和沱江汇合口过渡段沙卵石浅滩.它将河道分为左右两槽,右槽较浅,左槽较深,滩段碍航状况较为严重,船舶过滩比较困难,是叙渝段枯水期重点维护滩险.在基于河床演变规律和分析碍航原因的基础上,结合河工模型试验研究,分析了采取疏浚和筑坝整治措施后滩段的通航水流条件.通过对整治前后的效果比较,发现碍航险情消失,达到了设计...

| Abstract: | Jinzhongqi shoal,the confluence of the Yangtze River and Tuo River transitional shallow sand bed,by which the river is divided into two slots.The left slot is deeper than the right one.This beach section is of more serious navigation condition that ship has more difficulty to pass this section.And this section is the key maintenance of Chongqing section of rapids in the dry season.Firstly,the evolution rule of riverbed and the cause of navigation blocking are analyzed;and then combining with the study on ph... |
