在建筑火灾和一些紧急突发事件中,特殊人群不能使用正常人的紧急疏散通道,也不能达到正常人的疏散速度,而这个问题在目前的消防设计和消防规范中基本上没有得到解决.在分析特殊人群疏散行为规律的基础上,选取医院住院楼的标准层进行了疏散模拟,得出了一些重要结果,对疏散设计具有指导作用.最后提出了特殊人群的疏散设计方法,主要包括AORS系统和特殊报警系统的设计.  相似文献

在封闭建筑和开敞空间的道路设计中,常常忽略道路转角对人员疏散的影响。目前有关道路转角对人员疏散影响的研究多是定性分析,然而对于人员高度聚集的场所,任何细小的疏忽都会导致在火灾和人为灾害疏散过程中的拥堵,甚至造成严重的事故。因此,道路转角对人员疏散的影响不容忽视。本文借助人员疏散仿真软件S IMULEX,定量分析了道路转角对人员疏散的作用,获得了一些规律性的认识,并针对步行道路转角的设计给出了一些建议。  相似文献

Over 13 million Humanitarian Daily Rations (HDRs) have been distributed by NGOs, international organisations and the US military since 1993. In that time, not a single technical end-user study of HDRs has been published. Nor have practical guidelines been established for HDR distribution or use. This paper seeks to establish a baseline of knowledge concerning HDRs, surveying their history, composition and distribution. Criticisms of the ration are reviewed. A comprehensive evaluation is required to understand and improve HDR distribution, end-use, perceptions, design and nutritional contents. HDRs must also be added to technical guidelines on planning nutritionally adequate rations.  相似文献

Especially since the terrorist attacks of 11 September 2001, governments worldwide have invested considerable resources in the writing of terrorism emergency response plans. Particularly in the United States, the federal government has created new homeland security organisations and urged state and local governments to draw up plans. This emphasis on the written plan tends to draw attention away from the process of planning itself and the original objective of achieving community emergency preparedness. This paper reviews the concepts of community preparedness and emergency planning, and their relationships with training, exercises and the written plan. A series of 10 planning process guidelines are presented that draw upon the preparedness literature for natural and technological disasters, and can be applied to any environmental threat.  相似文献

火灾中人群疏散延迟时间的研究   总被引:1,自引:0,他引:1  
田玉敏 《灾害学》2007,22(4):95-99
火灾中人员的疏散时间主要包括疏散前的延迟时间和在通道上的疏散时间。对疏散延迟时间的分布及其对疏散时间的影响进行了研究,利用Building Exodus软件对实际工程进行了模拟,并得出了一些重要的结论。这些结论对于修正传统疏散时间的工程计算方法、制定合理的人群管理对策具有重要的指导作用。  相似文献

火灾中的人员疏散是个复杂的过程,受到诸多因素的共同影响,传统的人员疏散可靠度分析常常忽略这些因素之间的相互作用。为更准确地计算出火灾中人员疏散的可靠度,本文以某地铁车站为例,借助人员疏散仿真软件buildingEXODUS与火灾模拟程序FDS,分别得到人员所需安全疏散时间(RSET)和可利用安全疏散时间(ASET)。在此基础上,构造人员安全疏散极限状态方程,利用一次二阶矩理论求得安全疏散可靠概率。由于能够较好地反映疏散过程中各影响因素之间的相互作用,因此,采用本文提出的可靠度分析方法能够得到更合理的结果。  相似文献

地铁列车火灾中的人员疏散仿真研究   总被引:1,自引:0,他引:1  
近年来,随着城市人口的不断激增,地铁行业也随之蓬勃发展,地铁列车已经从城市交通的辅助角色转变成人们生活中的关键需求,因而做好地铁的消防安全工程势在必行。针对列车火灾的人员疏散问题进行了模拟分析,考虑列车车厢内4种人员密度疏散的场景,通过软件模拟分析,将结果与规范计算所得结果进行比对,较为真实可靠地反映了人员密度对疏散的影响,并在此基础上提出相关建议。  相似文献

隧道的横通道作为人员疏散的安全地带,其间距的设置在人员安全疏散中是至关重要的。以雪峰山隧道为工程实例,从人员安全疏散的观点出发,阐述了一种计算横通道间距的方法,并简述了方法的应用。首先根据特长隧道火灾特点,模拟分析特长隧道四种不同火灾场景下的典型自然疏散过程,并运用火灾模拟软件FDS4.0计算四种火灾场景在不同横通道间距情况下的危险时间,然后与相应的包含人员疏散行为特征的疏散时间相比较,得出该隧道最适宜的横通道间距为270m,并分析其经济性。其方法和结论可为特长隧道消防系统的设计、紧急疏散方案和引导指挥体系的建立提供理论依据。  相似文献

Painting an accurate picture of the situation on the ground in countries in crisis is vital for the efficiency of humanitarian aid and reconstruction agencies. This study describes a method for standardising and mapping the plethora of open-source information. The test site for the study is post-conflict Iraq. Important information on aid distribution, reconstruction and security in Iraq can be derived from the reports of humanitarian aid agencies and the media, before being formatted, inserted into a database and mapped. The product is a visual, cartographic structure of otherwise random information, showing which organisations are working in the country, which thematic and geographic areas are being prioritized in the field, and which areas most frequently experience security events. This type of mapping not only highlights the overall working environment within different parts of the country, but it may also serve as a decision-making tool for donors and humanitarian aid agencies planning to deploy personnel.  相似文献

城市避震疏散场所公园绿地面积指标的研究   总被引:6,自引:0,他引:6  
前人研究城市绿化和避震疏散场所的都很多,但都是把两者分开来研究。本文把两者结合起来,在研究避震疏散场所的基础上,以尹之潜、李荷提出的震害预测方法和谢礼立归纳的房屋遭遇地震时的破坏情况为基础,以人的需求为本,结合定性和定量2种方法,分别对城市建成区、发展建设区和规划新城区避震疏散公园绿地指标进行研究。按本文提出的避震疏散公园绿地指标规划城市避震疏散场所,既能满足城市避震疏散的目的,又能提高城市绿化率。  相似文献

In late 2003 the Feinstein International Famine Center, in partnership with institutions in London, Geneva and Washington, organised a series of consultations on the future of humanitarian action post-Iraq. This article is based on those discussions. A number of recurring concerns are elaborated, ranging from the perception of humanitarianism as a Northern-driven and Northern-controlled enterprise, through the politicisation of security and the devaluation of the protective power of emblems, to the very nature of how the crisis in Iraq is perceived. The article explores the implications of such issues for humanitarian workers and their institutions. It concludes by framing an agenda for action by the humanitarian sector.  相似文献

为研究水下公路隧道纵向疏散通道加压送风系统的关键设计参数,结合纵向疏散通道的特点,借鉴一般建筑加压送风系统的设计要求,提出了纵向疏散通道内加压送风量的计算方法,并通过数值模拟方法对纵向疏散通道加压送风系统进行了研究。结果表明,利用风速法计算得到的送风量比压差法计算得到的结果大20倍左右,并且压差法计算送风量时受疏散口缝隙宽度影响较大,工程适用性差。通过数值模拟可知,疏散通道内的送风风速达到1.5m/s时即能够满足人员安全疏散要求,这与风速法计算的结果一致。研究结果可供采用纵向疏散模式的隧道疏散通道加压送风系统设计参考。  相似文献

Linking community knowledge with modern techniques to record and analyse risk related data is one way of engaging and mobilising community capacity. This paper discusses the use of the Geographic Information System (GIS) at the local level and the need for integrating modern technology and indigenous knowledge into disaster management. It suggests a way to mobilise available human and technical resources in order to strengthen a good partnership between local communities and local and national institutions. The paper also analyses the current vulnerability of two communes by correlating hazard risk and loss/damage caused by disasters and the contribution that domestic risk maps in the community can make to reduce this risk. The disadvantages, advantages and lessons learned from the GIS flood risk mapping project are presented through the case study of the Quang Tho Commune in Thua Thien Hue province, central Viet Nam.  相似文献

Successful problem-solving is usually based upon a sound knowledge of the problem. Where the problem is a hazard, the impossibility of a 'solution' in terms of complete prevention is well known but proper problem assessment is still required. Detailed hazard zone mapping can be a valuable aid to planning to reduce hazards and to avoid disasters. A map is a powerful visual medium for conveying information where awareness of disaster proneness amongst public officials and others is limited. However, a map is also a comparatively limited medium for analysing risks and is most useful to planners if combined with detailed supporting documentation. Maps and related documents are particularly useful if they provide a complete assessment of risk, are periodically updated, are integrated with the planning process and are systematically compiled and presented at an appropriate scale. Map scale often presents problems. The larger the scale, the less limited the map will be in recording useful detail but updating becomes more costly and therefore less likely. The Water Authorities Section 24(5) surveys are remarkably detailed and are valuable planning and research materials. They demonstrate the widespread nature of flooding problems and the need for decades of flood alleviation and drainage expenditure in England and Wales. Further standardisation of content and presentation could enhance the value of the survey reports but their value depends ultimately upon regular and systematic updating.  相似文献

This paper presents the results of research carried out to improve emergency response activities in earthquake-prone areas of Iran. The research concentrated on emergency response operations, emergency medical care, emergency transportation, and evacuation—the most important issues after an earthquake with regard to saving the lives of victims. For each topic, some guidelines and criteria are presented for enhancing emergency response activities, based on evaluations of experience of strong earthquakes that have occurred over the past two decades in Iran, notably Manjil (1990), Bam (2003), Firouz Abad-Kojour (2004), Zarand (2005) and Broujerd (2006). These guidelines and criteria are applicable to other national contexts, especially countries with similar seismic and social conditions as Iran. The results of this study should be incorporated into comprehensive plans to ensure sustainable development or reconstruction of cities as well as to augment the efficiency of emergency response after an earthquake.  相似文献
