武汉沌口码头工程河段河床演变趋势分析

Trend on fluvial process of dock works reach in zhuankou in wuhan

沌口商品汽车滚装专用码头工程位于长江武汉河段的白沙洲分汊河段,笔者在文中对拟建码头工程河段河道历年冲淤变化特点进行了分析,结果表明,近几十年来,码头附近河段河势稳定,岸线、深泓线以及深槽边滩位置相对较稳定,岸线与水流较平顺.在不同水文年中,洲滩局部仍会出现冲淤交替变化,但河势不会发生大的变化.多年来河床基本处于相对稳定状态,具备兴建码头的水域条件.

Zhuankou special dock works of the commodity car installed rollers locate at the Baishazhou braided reach in Wuhan Reach. The characteristics of the sand scour and deposit in the past years are analyzed on the planed dock works reach. The results indicate that in the near many years, river regime near the dock reach is stable, the place of the bank line, the thelwge and the bank shoals are steady relatively, the bank line and water flow are smooth. In different hydrographic years the alteration change of the sediment scour and deposit will still occur in the partial bars and shoals. But the great change of the river regime will not happen. The river bed is relatively stable in the most years and has the water area situation of constructing the dock.
