伶仃洋是华南具有重要航运功能的河口湾,在其东西两岸分布着广州港南沙港区、深圳港西部港区、中山港等重要港口,伶仃航道和铜鼓航道是广州港和深圳港的重要出海通道。伶仃洋港口航道的主要问题是泥沙淤积问题。基于现场实测资料分析、卫星遥感分析、泥沙水槽试验、港池淤泥密度测量与分析等手段,对伶仃洋港口航道的泥沙问题进行综合分析和研究,包括泥沙运动动力条件特征、泥沙来源与运移形式、悬沙和底质特征、港口航道泥沙淤积特征及机理、泥沙水力特性试验、浮泥及适航水深利用等,并根据伶仃洋港口航道泥沙特点提出南沙港区港口航道维护对策。  相似文献

文章基于深圳铜鼓航道实测回淤监测资料,研究了铜鼓航道段的回淤特征,探讨了航道回淤机理。研究结果表明:(1)铜鼓航道沿程回淤分布曲线出现两个锋值,回淤主峰值位于K21里程以北区段,次峰值位于K10~K16里程区段,K7~K9里程区段、K17~K18里程区段回淤较小;(2)铜鼓浅滩滩面泥沙及上游来沙是铜鼓航道回淤泥沙的主要来源,航道回淤的主要形式为悬沙落淤;(3)铜鼓航道K21以北航道回淤较大与铜鼓浅滩东部河口峰的存在导致泥沙易于落淤;(4)受洪季上游来沙量大、台风浪较大的影响,铜鼓航道洪季淤强相对较大。  相似文献

基于珠江三角洲河口湾主要航道的现状情况,在分析航道回淤影响的基础上,对航道选线、整治思路等相关航道整治问题进行了研究。认为河口湾航道回淤受上游水沙条件、潮流波浪情况、采沙等人类活动等因素影响,台风骤淤情况不明显。航道选线宜选择天然深槽、走向与潮流动力线一致、尽量避开强浪区。整治措施宜采用疏浚结合局部碎岩清礁,宜分期实施。广州港出海航道和崖门出海航道有进一步提升等级的空间,铜鼓航道可考虑适当调整航槽位置,横门出海航道与九洲港航道开发深水航道的时机和条件尚不成熟、近期不宜过度开发。对河口湾的航道开发与港口建设具有重要的参考价值。  相似文献

<正>1 前言 深圳西部港区位于珠江口伶仃洋东岸,矾石水道与暗士顿水道的交汇处.建港时间虽短,但发展速度快,年吞吐量近3000万t,为全国十大港口之一.由于目前通航的马湾水道即急水门和咸汤门航道引航被动,通过能力差,已不适应深圳西部港区的发展乃至深圳特区经济高速发展的需要,因而开辟铜鼓航道势在必行.本文根据水文泥沙条件和潮流泥沙淤积模型试验,经综合分析比较推荐铜鼓西航道为开发航道,为深圳西部港区航道开发提供了科学  相似文献

Recent measurements of wave induced hull strain and flexure in RN warships are presented together with the derivation of the current design criteria for extreme hull girder bending loads. The history of the development of the shipboard instrumentation used is given and recent developments to improve the quality and ease of analysis of the data are described. An unexpectedly high transverse asymmetry in the longitudinal strains measured in destroyers is shown to be the result of a combination of vertical and lateral bending in oblique seas. Finally recent theoretical comparisons between the loading of Deep-Vee hulls and conventional UK rounded bilge hulls are presented which demonstrate the higher loading experienced by this type of hull form.  相似文献

Despite the many socio-economic similarities between Sweden and Norway, differences in jurisdiction, organisation, cooperation, and financing of long-distance passenger train and coach services have led to the development of four distinctively different ways of serving the markets. This paper describes how the train and coach markets have developed in the two countries, with emphasis on regulatory and industrial structure and a couple of performance variables.Looking at passenger rail, both countries separated infrastructure from operation over a decade ago. However, while Norwegian rail is characterised by an almost monopoly supplier, rail services in Sweden are partly decentralised to the responsibility of county authorities and are widely subjected to competitive tendering. The rest of the network is about to be opened up for on-the-track competition. Swedish Rail (SJ) has spent the last decades consolidating its core business (passenger rail) and sold out its other businesses. In contrast, the Norwegian state rail (NSB) has expanded its business to become a major bus operator and property owner, with extensions also into the Swedish market.The coach industry was more recently deregulated in both countries. The Swedish coach market is dominated by privately owned companies operating services to and from Stockholm. In Norway, state-owned NSB is a major coach operator on medium distance routes, and is also the largest partner of Nor-Way Bussekspress which totally dominates long-distance coach services. Further, the Norwegian coach market is characterised by cross-ownership and cooperation which has enabled an extensive route network which covers most of Norway.We find distinct differences in achievements in the two modes and in the two countries. Swedish rail services have succeeded in winning market shares and in renewing and developing both infrastructure and service levels to a greater extent than the Norwegian model. On the other hand, the Norwegian coach market seems to be more developed and efficient compared to its Swedish counterpart.The paper concludes with a discussion on the possible links between the different approaches and the performance observed, with the aim to stimulate further and more detailed research on some important issues.  相似文献
