凸岸

河口区弯道凸岸段水深治理，在不改变大河势前提下，其技术难度较大。

Regulation of bend convex bank channel at river estuary was of great technical difficulties under the prerequisite of not changing the river regime .

突出体现在水流失去平衡，产生凹岸高、凸岸低的横比降，而且弯道急流表面还将产生水冠较大的菱形冲击波。

These mainly behave at that the water flow losses it 's instability and generates the transverse gradient that the water surface of concave bank is higher than convex bank , and that the big diamond impact wave even occurs on the water surface .

一般凹岸深水岸线多，而凸岸浅水岸线多，河流束窄段、有节点控制的地方深水岸线多。

And also there is much deep water in river constriction segment and in the area which has kickpoint controlled .

弯道水流在做曲线运动时形成螺旋流，而它正是弯道凹岸冲刷和凸岸淤积的根本原因。

When curved channel flow made curve motion , spiral flow was formed which was just fundamental reason for concave bank erosion and convex bank sedimentation in bend .

在曲率为90°时，河道凸岸从进口到弯顶河床冲刷，弯顶以后泥沙淤积。

In 90 ? curved channels there is erosion from channel beginning till to middle of the reach after that there is significant deposition at inner bank side .

分析表明，蓄水后土脑子河段已基本完成由凸岸深切河曲向宽浅河曲变化的过程，将会进一步转化为凹岸深槽的河曲。

The results reveal that after the impounding , Tunaozi Shoal transformed basically from convex-bank entrenched meander to shallow broad river , and will further develop to a concave-bank deep channel .

弯道进口处的凸岸、弯顶及其以下部位都是河岸崩塌的严重区域，凹岸崩退速率较大。

Bank will seriously fail at the inner of the upstream , apex and the outer of the downstream in curved reach , of which there is a greater erosion rate at the apex .

结果表明：只要采取合理的工程措施，就能保证凸岸取水口取到表层清水，保证水电站的良好运行。

The results showed : As long as taking reasonable measures , we can guarantee the water inlet of convex bank fetch top layer clear water to ensure hydraulic power station work in good condition .

本文阐述了长江镇扬河段近百年来河床演变对镇江港的影响，镇江港由凹岸的深水良港，演变为凸岸的挖入式港池；

This article expounded the effect of the riverbed evolution of Zhenjiang-Yangzhou section of the Changjiang River over the past century on Zhenjiang port which used to be a deepwater harbour with concave bank and has been developed into a completely dredged port with convex bank .

在所有结构组合条件下，弯道水面都有较大偏斜和扭曲，并且在弯道中部主法线方向上，基本为凹岸水面高凸岸水面低的规律。

Under the all different structures ' combination , the water surface had large bias and turn-around in the torturous path , and in the middle of the path along the longitude , there had the regularity that sink bank surface was higher than the convex bank one .
