东莞市立沙岛海堤加固设计与基础方案研究

台风及暴潮是珠三角沿海地区侵蚀海堤的主要自然灾害之一,为了该沿海地区的社会经济财富损失减少到最低并且海堤工程投资还要最为经济,所以该地区的海堤加固设计与基础方案就极为重要;东莞市的海堤大部分建筑在软土地基上,根据整体稳定计算确定的断面往往比较大,而且通常在设计时还要考虑到亲水及生态景观等要求,这样诸多因素造成海堤断面设计显得比较复杂,因此堤顶高程的计算和堤防基础加固方案就尤为重要,不仅影响到海堤的安全而且还直接影响到经济投资,本文针对东莞市立沙岛海堤提出堤顶高程计算方法与推荐出合理的基础处理方案。     

低桩承台直立结构在海堤工程中的应用

针对深圳机场三跑道海堤工程场地软弱土层深厚,海堤建设需要满足对广深沿江高速的位移限制要求,且海堤堤顶高程不能超过15 m安全限高线等系列问题,提出低桩承台直立式海堤结构,并采用水泥搅拌桩进行基础加固处理。采用经验公式并通过波浪物理模型试验确定合理的堤顶高程,且采用国际通用软件Plaxis 3D进行结构受力分析,证明该海堤方案能有效控制土体侧向变形。针对海堤需满足使用100 a的防腐问题,钢结构采用重防腐蚀涂层、牺牲阳极阴极保护和混凝土包覆联合防腐措施,确保海堤满足设计保护年限。

海堤可视化监测系统开发与应用

海堤作为一种特殊的水工建筑物,经常受到潮汐、台风等因素的影响,运行工况复杂。结合海堤运行的特点,利用Arc GIS强大的地理信息处理能力和Arc GIS Engine丰富的组件库,在Visual Studio(简称VS)平台上借助C#编程语言实现了海堤可视化监测系统的开发。系统内置的数学建模分析模块能够调用实时监测数据并对其进行分析预测,便于及时了解海堤的运行状态,保证海堤安全。工程实例证明,该系统较好地实现了海堤安全监测中的二维与三维可视化操作,对空间数据库和属性数据库以及安全监测数据进行了系统的管理,内置的数学建模分析模块对监测数据的分析和预测结果较好。

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.
