三峡库区斜坡式码头靠泊能力评估方法研究

随着三峡库区航运经济的发展,船舶大型化已成为发展趋势.为确保港口安全生产,需要对已建码头的靠泊能力进行评估.现有评估主要采用现状调查和测试的方法得出评估结论,很少涉及评估方法的研究.综合分析影响斜坡式码头靠泊能力的因素,提出靠泊能力评估方法,并结合工程实例,做了详细的技术说明,为正确进行斜坡式码头靠泊能力评估提供了一套可行的方法.     

三峡库区架空直立墩式码头靠泊能力评估研究

三峡库区正常蓄水后,库区航运条件得到极大改善。由于码头存在靠泊超设计船型船舶的情况,因此,对库区现有码头进行靠泊能力评估是十分必要的。本研究通过分析和研究架空直立墩式码头的靠泊能力,提出结合原有设计和码头实际运行情况,并通过有限元计算分析超设计船型靠泊时码头结构实际响应的综合评估方法。该方法可为类似码头靠泊能力评估提供参考。

通航安全评估中船舶操纵模拟试验方法的应用

结合开展码头工程通航环境安全评估的专题研究工作,探讨船舶操纵模拟试验方法在码头工程通航环境安全评估中的应用,该方法主要包括通过船舶操纵模拟器的模拟试验获取的模拟船舶运动参数和运动轨迹,应用航迹带宽度、潜在操船水域、效用函数和靠泊操纵危险度等概念,对拟建码头工程所需的航道宽度、船舶回旋水域和靠泊操纵的安全性进行分析和评判。实际应用表明,该方法能客观、合理地分析与评估码头工程的通航安全,具有较好的应用价值。     

船舶靠泊组合下的泊位年通过能力仿真研究

对某改扩建的油码头，首先采用基于设计规范的设计方式对泊位年通过能力进行初步计算。由于任意泊位停靠船舶的船型大小会对其它泊位停靠船舶的船型大小产生一定约束（即船舶靠泊具有组合约束），考虑到这类船舶组合靠泊对码头泊位年通过能力的影响，引入仿真技术对船舶靠泊组合约束下的码头泊位年通过能力进行仿真计算，并将仿真数据与基于设计规范方式得到的数据进行比较和分析，为船舶靠泊组合约束下的泊位年通过能力的计算提供新思路。     

港口码头靠泊能力核查管理工作探讨

码头结构相对固定,是确定码头靠泊能力的内在因素;船舶航经水域的通航条件处于变化之中,是确定码头靠泊能力的外在条件.码头靠泊能力核查,应以码头结构为主,且提升码头等级所提出的限定条件不得超过相关规范的要求及当地水文气象要素的平均值,而不能因核查论证时的某一通航条件限制了码头的靠泊能力.

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.
