海外港口绿地项目规划方法与原则

随着"一带一路"倡议的不断推进,中国的设计单位越来越多地参与到海外港口绿地项目的规划工作中。由于国内目前还没有成熟的指导性文件对规划的方法和原则进行说明,本文结合吉布提与印尼港口项目实例,介绍海外绿地项目规划应包含的内容和应遵循的工作流程,并总结出规划的原则,包括顺应自然地形、保护自然环境;土方挖填平衡;弹性发展,注重起步工程实施性;按需集约化布置、区块划分明晰;综合考虑经济效益的基础上保证项目每一期的自生性。这些工作实践的总结可为未来海外港口绿地规划工作提供借鉴。

单波束测深仪水深粗差检测与修正新算法及其效果

单波束测深仪是现代海洋测量尤其是内河水下地形测量中的主要测量仪器。即使在声速设定正确的前提下,单波束测深仪的观测值仍然会有各类型的粗差。针对其原始水深值粗差处理问题,创新性地提出"地形链"的概念,设计了一种新的针对单波束测深仪水深观测值的粗差检测与修正算法,针对长江流域的单波束测深数据进行处理,结果表明算法对各类粗差有明显的检测和修正效果。     

海港码头前沿设计水深计算建议

在计算海港码头前沿设计水深时,目前国内项目设计的依据是《海港总平面设计规范》JTJ211-99中第4.3.5条款;而在海外项目设计中,设计依据则为国际通用的规范;随着海外项目日益增加,对比国内外规范异同,对于国内外工程设计具有重要意义。笔者在计算海港码头前沿设计水深时,对比了国内、国外几种主流规范或手册的计算思路,对国内规范提出建议。

长江口水域高精度水文测量四维无缝基准的建立及应用

在宽阔的潮汐河段,由于潮汐和地形的影响,大范围的同步水文测验的精度和可靠性受到了很大的限制。为了得到高精度的水文测量成果,使同步观测资料和时间序列资料具备良好的可比性,需要建立高精度的平面基准、高程基准和速度基准。理论和实践表明,建立大范围内的高精度的GNSS(global navigation satellite system)控制网,基于RTK(real-time kinematic)测量方式进行三维水深测量、基于RTK的速度参考进行流量测量,是在大范围条件下开展高精度同步水文观测的有效途径。

Recent progress on wave induced loading measurements in warships

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.

Impact of regulation on the performances of long-distance transport services: A comparison of the different approaches in Sweden and Norway

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.
