港口安全管理评估量化研究

对港口安全管理体系进行量化评估,不仅可推进体系的不断完善,更可促进港口企业建立健全安全生产的自我约束机制。笔者在港口安全管理体系研究的基础上,综合考虑各类港口的不同情况,运用改进的层次分析法(AHP),建立港口安全管理体系的递阶层次结构模型和构造判断矩阵;通过对沿海,内河,大、中、小港口的调查和方根法数值计算,确定评估体系中各评估要素、评估要点的权值;提出了保障港口安全生产的港口安全管理体系基本评估要点;研究完成量化的港口安全管理评估系统。该评估体系可定量评估港口安全生产状况、港口安全生产程度,及时发现港口在安全生产及安全管理方面存在的隐患、不足与缺陷等问题,从而可及时而有效地预防和控制港口系统重大事故的发生。

Towards deliberative and pragmatic co-management: a comparison between inshore fisheries authorities in England and Scotland

In seeking to answer the question ‘who should be included in fisheries co-management?’, a constructive critique of the existing co-management literature is provided by filling the gaps of Habermas’s deliberative theory of democracy with Dewey’s pragmatism. Three conditions for ensuring democratic co-management are extrapolated from the theories: actors’ authority over decision making (empowerment), actors’ diversity (membership), and the right to self-nomination (procedures for external inclusion). The theoretical insights developed are supported with two examples of co-management institutions for inshore fisheries in the UK: Scottish Inshore Fisheries Groups (IFGs) and English Inshore Fisheries Conservation Authorities (IFCAs).     

Research on Methods for Building Volcano Disaster Information System--taking Changbai Mountain as an example

1IntroductionAs a many-volcano-distributed country,China is covered with many volcanoes and lava rocks.A-mong the one-thousand-or-so volcanoes,Changbai Mountain Volcano,Wudalianchi Volcano,Tengchong Volcano and Ashikule Volcano of West Kunlun are the mostlatentcatastrophic erup-tive active volcanoes.In recent years,the activity of the earth' s crust in some volcanic areas isobviously becoming increasing violent.Butfew scholars have monitored and evaluated volcano inChina.So building VDI…

基于能量合成法的塔式结构刚度识别研究

在Rayleigh能量法和Southwell's频率合成法的基础上,将结构的振动基频表示为由各变形元和惯性元组成的子系统频率的合成,其中变形元为结构的弯曲变形和剪切变形,惯性元为结构的分布质量和塔顶附加质量。通过选取满足边界条件的挠度函数,建立了底部固定、顶端带有附加质量的塔式结构基频与刚度的关系,因此可通过测量结构的振动基频识别出塔式结构的抗弯刚度和抗剪刚度。以某钢塔为计算实例,采用该算法推导出了结构振动基频与弹性模量的关系,只要知道截面的几何尺寸和材料性质,便可快速识别出各截面的刚度。有限元空间建模计算结果证明了本文提出的算法具有较高精度。该方法适合底部固定的塔式结构,可为复杂空间塔式结构使用状态的监测与评估提供参考。     

Factors in offshore planning that affect the risk for major accidents

The purpose of this paper is to systematically analyse a typical planning process in the offshore industry from the perspective of causes of major accidents, with the ultimate aim of identifying factors that affect the risk for major accidents occurring. We first study and describe a typical planning process for offshore oil and gas operations in Norway. Then we analyse a number of theories of major accidents, to see how the different theories and their explanations of causes and contributing factors can be of relevance for future plans and planning processes. Finally, we review accident investigations to search for evidence of how weaknesses in planning processes can contribute to major accidents through the above identified factors. Also, we try to identify any additional factors that have not been recognised through the theoretical review. This provides empirical support for the theoretical basis. Thirteen factors which directly or indirectly can influence the planning process causing a major accident potential are identified. These are exemplified through a review of investigation reports. The paper suggests that planning process should focus more on increasing quality in the plans at an early phase, with examples from incidents, and illustrate the relation between planning quality and potential for major accidents.
