防波堤工程中的抛填施工技术分析

在现代交通运输业的驱动下,防波堤工程中的抛填施工技术在当今施工项目中占有重要地位。本文以香港某水域防波堤工程的施工为例,基于当地自然环境以及交通状况,对水上抛填施工工艺以及抛填质量控制进行规划设计,为后续防波堤工程中的抛填施工工程提供价值参考。     

自制水上移动平台在小潮差海域防波堤水面以上部分抛石施工的应用

在小潮差海域,防波堤水面以上块石抛填施工,传统抛石船抛填施工需要乘潮作业[1]和多次补抛作业,施工效率低,防波堤形成有效抗风浪断面周期久,施工风险大。本文结合海南国电防波堤施工,介绍一种在抛石船船头设置悬挑结构,和抛石船共同构成移动的水上抛石平台,提高防波堤水面以上部分抛石效率的技术。

小开底驳船在窄桩间大棱体高桩码头抛石施工中的应用

大连长兴岛公共港区通用泊位高桩码头为窄桩间大棱体接岸抛石结构,皮带机抛石船和方驳配反铲抛石船均无法满足工期要求。采用自制的小开底驳船抛石施工工艺,通过合理的分区分层抛填,跟踪测量监控,适时调整施工参数,确保了因抛石引起的桩位偏差（没采取夹桩工艺）在规范允许的范围内,大大提高了施工效率,有效解决了抛石施工难题,为类似高桩码头抛石施工提供了经验。

黄骅港浅海防波堤的施工

黄骅港南防波堤工程是我国在软基上施工的最长的防波堤工程，首次采用高强土工织物进行软基加固，同时又是在浅海水域进行大规模砂石料抛填，文中叙述了防波堤施工中所采取的新工艺及主要施工工艺过程。     

灌注桩水上作业平台施工工艺优化

由于防波堤护坡和护脚的抛填均采用规格较大的块石，常规灌注桩水上作业平台的螺旋管打设困难，导致平台基础体系难以形成。根据钢平台原设计方案出现的系列问题进行优化设计，最终采用岸侧回填块石+搭设2排贝雷架、外侧1排螺旋管桩的基础支撑体系。结果表明：平台基础体系结构受力和承载力验算合格，灌注桩施工时钢平台未产生较大的滑移突变，沉降较均匀。该水上作业平台安全可靠、便于施工。

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.
