航道等级

在此基础上实现了航道等级分析、水深分析和挖方计算等应用。

Basing this model , many further application can be realized , such as waterway classification analysis , water deep analysis and dig area calculation .

对国家内河航道等级划分的新思考

New Consideration on Grading of National Inland Waterway

航道等级的合理划分是水运可持续发展的保证。

Rational grading of waterway is the guarantee for sustainable development of water transportation .

但目前澜沧江航道等级依旧很低，比起国内其他内河航道来说仍有较大差距。

But the waterway of Lancang river is still bad . Compared with other domestic inland waterway , there is a big gap .

流域空间结构演化主要受航道等级、城市居中性以及腹地大小的影响。

Basin spatial structure evolution is affected by factors of rank of riverway , geometric centrality of cities , and size of hinterland .

设计技术标准不只局限于航道等级对航道尺度的要求，还根据降低流速和减缓比降的需要，将滩口或相应部位作加宽、加深处理，以便改善流态，满足航行要求。

The technology standard will not only satisfy the requirement of the channel grade , but also make the corresponding section of the shoal wider and deeper according to the requirements of slowing down the current velocity and slope .

上游水电工程的开发，将极大地促进航运事业的发展，为改善下游通航条件、提高航道等级和尺度提供了良好的条件。在此基础上实现了航道等级分析、水深分析和挖方计算等应用。

The hydroelectric development in the upper basin of the Yangtze River will greatly promote the development of navigation . Basing this model , many further application can be realized , such as waterway classification analysis , water deep analysis and dig area calculation .

比如说，泊位和航道等级偏低，不能适应船舶大型化发展趋势；港口功能分区有待调整；铁路通过能力不足，制约港口的进一步发展等等。

For example , berth and channel level is low , cannot adapt to the development trend of large-scale ship ; Port function area needs to be adjusted ; the ability of railway is insufficient , which restricts the further development of port and so on .

第二松花江航运发展落后，主要表现在航道等级低，多数航道仍处于自然状态，通过能力差，航运在五种运输方式中所占比重非常小；

It falls behind , expressing primarily in waterway order is low , most waterway is still placed in state of nature , passed capacity badly , the density occupied of shipping in five kinds of conveyance methods is very small , the basic facilities of shipping are backward .

包括推进船舶标准化工作，推升航道等级；推进航运结构调整，提高水运物流竞争力；改革船闸通航管理体制等来提高西江航道服务水平从而带动沿江区域物流的发展。

Include promoting the standardization of the ship , pushing channel level ; promoting the shipping of structural adjustment , improving the competitiveness of water transport logistics ; reforming ship lock management system to improve the West River waterway services so as to drive the development of regional logistics .

三峡库区支流航道技术等级定级及其应用西欧内河航道分级标准

Preliminary Study and Its Application of Navigation Grading Standard Planning of the Tributary Channel in TGP Reservoir Area West-European inland waterway classification scale

由于连云港内河航道历史上等级偏低的原因，内河港口小而弱，管理上存在着体制上的不健全和监管缺位等问题。

By the historic reason as low grade of inland navigation channel of Lianyungang city , the inland port is still found small and weak with unsound system and incomplete supervision .

合理地进行航道改造及提升等级，构建较完善的内河航道网，对宁波市内河航运的振兴和发展起着决定性作用。

It is decisive effect for the navigational boom in Ningbo City to renovate the waterway and increase its capacity , and to make the perfect to the inland waterway network .
