扬巴二期改造项目码头工程陆上钢引桥安装施工技术

扬巴二期改造项目码头工程钢引桥安装平面位置为连续四跨垂直于长江,陆上钢引桥安装位置距离江边距离远,安装钢引桥的重量和几何尺寸较大。钢引桥无法采用陆上运输,需通过水运运输至施工现场,根据现场实际情况,陆上钢引桥的安装存在较大的难度。文章对陆上钢引桥起吊上岸、陆上横移施工技术进行分析讨论,克服了钢引桥安装位置距离远、吊幅有限的技术难题,成功地将重量和几何尺寸较大的钢引桥安装就位。     

半活动式钢引桥在大水位差旅游浮码头上的应用研究

活动钢引桥在浮码头中应用较为广泛,大水位差下需设置两跨或两跨以上钢引桥来连接浮码头与岸坡,两个钢引桥之间通常设置升降架来调整钢引桥的高度,传统钢引桥的升降以人力或机械动力来实现,需要专人管理。本文提出无动力半活动式钢引桥的连接方式,钢引桥之间采用浮式平台连接,浮式平台作为钢引桥的支点。高水位依靠浮力支撑浮式平台,低水位利用定位桩牛腿支撑浮式平台。

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.
