京沪铁路电气化工程的设计与创新

京沪铁路是我国"八纵八横"铁路网的主骨架,是世界最繁忙的铁路运输干线之一。为实施国家能源战略,优化路网结构,提高运输质量,降低运营成本,推进东部地区铁路干线电气化成网,实施全国铁路第六次大提速,国家决定对京沪铁路进行电气化改造。根据京沪铁路的现状特点,结合铁路第六次大提速的总体部署,按照铁路《既有线提速200km/h技术条件》的要求,对京沪线电气化工程、200km/h提速改造工程、双层集装箱运输通道设计、信号配套改造工程的难点和重点以及设计的关键技术等方面大胆创新,取得了显著的社会效益和经济效益。

混凝土中装药方式影响爆破效果的数值分析

基于大型非线性动力分析软件LS—DYNA，采用著名的混凝土损伤Johnson-Holmquist-Concrete模型，针对无限混凝土介质中深孔爆破时的耦合装药方式和不耦合装药中的干孔、湿孔爆破，展开了对比数值计算，综合分析了它们在损伤分布、静水压力、振动速度和加速度以及动能等衰减上的差异，得出的结论具有一定的参考价值。     

冷藏箱用制冷机组的新发展

按照ISO830《集装箱术语》的规定,凡是具有隔热功能的集装箱均统称为“保温集装箱”(Thermal Con-tainers)。目前,在全球海运市场最为流行的是配有机械式制冷机组的冷藏集装箱(Mechanical Refrigerated Containers)。此外,还有使用消耗式冷剂的冷藏集装箱以及不带制冷机组的隔热集装箱等等。当前,在国际航运市场上的主流就是被简称为“冷藏集装箱”的前者。正如《集装箱化》杂志2004年第8期第3页关慎谦研     

Maritime liner shipping and the stevedoring industry: market structure and competition strategies

Globalization, liberalization, competition and spatial interaction are significant factors affecting the transformation of manufacturing industries worldwide. In the transportation and logistics industry, however, cooperation is becoming even more critical than competition in determining firms' efficiency. Cooperation has always characterized the liner sector in which strategic alliances, mergers and acquisitions have generated twin effects: notable increases in ship size and falls in freight rates. Meanwhile, the stevedoring industry is undergoing privatization-driven consolidation and the emergence of global pure terminal operators. This article focuses on vertical integration between global carriers and terminal operators. We address the following key current issues:

• dedicated terminals as a strategy for cutting costs and controlling integrated transport chains;
• the struggle for supply chain control, involving global carriers versus global terminal operators, driven by financial power and technical and managerial capability.

We close analysing one of the core problems of the market, namely the evolving role of the dedicated terminals. For the pure stevedores they represent an opportunity to secure a cargo, while in the hands of the liners they enable cost stability and the possibility to put pressure on pure terminal operators.

A study of passenger discomfort measures at the Hong Kong mass transit railway system

This note investigates the important attributes relating to the crowding effects at the Mass Transit Railway (MTR) stations in Hong Kong. Data was collected at two sets of three MTR stations to study the responses of the passengers due to the discomfort at crowded vehicles and platforms. Stated preference surveys were used to study the effects of passenger discomfort measures.
