北极水域船舶航行风险管理研究现状分析

全球气候变暖使得北极水域作为航运通道成为可能,作为连接中欧的最短海上运输通道,北极航道正融入我国"冰上丝绸之路"战略.然而北极水域通航环境复杂多变、脆弱敏感,给船舶安全带来了很多非传统安全风险.为明晰目前北极水域船舶航行风险管理现状,通过对北极船舶航行风险管理文献进行梳理,从风险管理的公约/规则和技术2个方面分析和探讨当前的研究现状和未来的研究方向.研究表明,北极水域船舶航行风险管理研究技术受限于数据的缺乏和不确定性.随着未来北极基础建设和装备的研发,基于模型的、静态的、层次的风险识别、分析和评估研究将朝着数据化、动态化、系统化的风险预测、预报和预警的方向发展.      

『的哥』告赢出租车公司

陕AU9057号出租车司机王全真去年8月21日行业检验时,其所在的长安县永衡出租车公司负责人因他们未在指定的保险公司投保而扣押了他们车辆的营运证,致使车辆无法正常营运两个月.10月10日,"的哥"王全真将该公司告上长安县法院,要求判令赔偿5000元营运损失并返还营运证.但在一审庭审时,被告长安县永衡公司否认扣押了司机们的营运证,原告司机当庭写出证据保全书,要求对被告的办公场所进行检查.法官在检查中发现了原告司机车辆的营运证.

Risk management modeling and its application in maritime safety

Quantified risk assessment （QRA） needs mathematicization of risk theory. However, attention has been paid almost exclusively to applications of assessment methods, which has led to neglect of research into fundamental theories, such as the relationships among risk, safety, danger, and so on. In order to solve this problem, as a first step, fundamental theoretical relationships about risk and risk management were analyzed for this paper in the light of mathematics, and then illustrated with some charts. Second, man-machine-environment-management （MMEM） theory was introduced into risk theory to analyze some properties of risk. On the basis of this, a three-dimensional model of risk management was established that includes： a goal dimension; a management dimension; an operation dimension. This goal management operation （GMO） model was explained and then emphasis was laid on the discussion of the risk flowchart （operation dimension）, which lays the groundwork for further study of risk management and qualitative and quantitative assessment. Next, the relationship between Formal Safety Assessment （FSA） and Risk Management was researched. This revealed that the FSA method, which the international maritime organization （IMO） is actively spreading, comes from Risk Management theory. Finally, conclusion were made about how to apply this risk management method to concrete fields efficiently and conveniently, as well as areas where further research is required.     

综合管廊穿越地下交通隧道的共建设计

以某综合管廊穿越地下交通隧道为例，分析讨论了两者的竖向关系及协同设计。综合管廊采用“管廊变舱+结构共建”的形式上跨交通隧道，通过调整管廊的舱室数量、净高、净宽，将管廊内敷设管线的重新排布，尽可能减少了管廊穿越对交通隧道竖向设计的影响，起到集约利用城市地下空间资源，减少工程投资的作用。
