油气储运系统钢结构设备地震火灾效应研究 总被引:3,自引:0,他引:3
预防和减轻油气储运系统地震火灾危险性是防震减灾中的重要课题。本文论述了油气储运系统的地震火灾特征及防火要求,对钢结构的防火涂料在遭到破坏和平时情况下的抗火性能进行了对比分析,并应用有限元法对油气储运系统中典型钢结构设备在地震火灾荷载作用下的抗火性能进行了数值模拟。研究结果表明,防火涂料遭到强地震荷载破坏后,钢结构的抗火性能大大降低。 相似文献

必须重视大型石油储罐的抗震问题 总被引:2,自引:0,他引:2
地震灾害是各种自然灾害中最大的一种灾害,而大型石油储罐则是石油化工设备中震害最大设备,因此必须重视大型油罐的抗震问题,本文从油罐的几何形状的荷载特征等方面说明了油罐震害之所以特别大的主要原因;指出了油罐的主要震害;并从四个方面说明了油罐的抗震理论是非常复杂的。 相似文献

With urban reformation and opening becoming deeper, the work of protection against earthquake and disaster reduction would
be more important. In this paper, some ideas are suggested about establishing the information system for emergency decisions
on protection against earthquake and disaster reduction in cities. The information system mainly includes a subsystem for
rapid evaluation of damage loss from earthquake (which includes input of seismic information, distribution of earthquake intensity,
evaluation of seismic fragility on all social factors and etc.) and a subsystem for the decisive information of seismic emergency (which mainly includes project of disaster relief, project
of personnel evacuation, dangerous degree warning for the dangerous articles-storing places and protection measures against
them, assistant decision on fire due to earthquake, location of head-quarter for providing disaster relief, and etc.). It is thought that the data investigation and collection about all kinds of buildings (including lifeline engineering)
are the most important and difficult work as establishing this system. 相似文献

研究以绵阳市为例,选取城市人口密度、固定应急避难场所服务区范围、派出所服务区范围、医院服务区范围、消防队服务区范围及重大危险源爆炸范围等6项基本因子,利用GIS技术和层次分析法(AHP)对城市地震灾后应急能力进行研究。得到的绵阳市地震灾后应急能力主要结论有2个。(1)处于中低灾害应对能力的区域占总研究区面积的60.28%,表明:绵阳市二环路内整体灾害应急能力偏低,防灾减灾风险较大。(2)灾后应急能力较弱的地区主要为园艺山片区、南河片区、小枧片区以及二环路东西沿线。研究成果可为绵阳市制定城市专项防灾规划提供指导和建议,研究分析方法亦可为国内其他城市的防灾研究提供借鉴。 相似文献

It is clear that the basic countermeasure against earthquake strong motion is to reinforce buildings and other structures. Realtime earthquake disaster prevention is a countermeasure during the earthquake itself and is different from realtime seismology. An EEW, earthquake early warning system, is required to trigger realtime earthquake disaster prevention. It is important to avoid too much trust in EEW for the disaster prevention. This paper describes the concept of an EEW and gives a brief history, which eventually led to the development of the UrEDAS, the urgent earthquake detection and alarm system, the first operational P-wave early warning system. A real-world example of disaster prevention by this system is described. Finally, the role of national or public organizations in earthquake disaster prevention will be discussed, with special emphasis on the situation in Japan. 相似文献

GIS-based risk assessment of grassland fire disaster in western Jilin province, China 总被引:4,自引:2,他引:2
Tong Zhijun Zhang Jiquan Liu Xingpeng 《Stochastic Environmental Research and Risk Assessment (SERRA)》2009,23(4):463-471
Grassland fire disasters have occurred frequently and adversely affected livestock agriculture and social-economic development
greatly in the grassland regions of Jilin province, China. Moreover, both the frequency of grassland fire and loss from them
are considered to be increasing with the global warming and economic development. This study presents a methodology for risk
analysis and assessment of grassland fire disaster, taking western Jilin province as a case study area based on geographic
information system (GIS). The composite grassland fire disaster risk index (GFDRI) combined the hazard of grassland fire,
the exposure of the region, the vulnerability and emergency response and recovery capability for grassland fire disaster of
the region were developed to assess and compare risk of grassland fire disaster in different counties in western Jilin province,
China using the natural disaster risk index method (NDRIM), analytic hierarchy process (AHP) and weighted comprehensive method
(WCM). Then, the risk degree of grassland fire disaster was assessed and regionalized in the western Jilin province, China
based on GFDRI by using GIS. It is shown that the most places of western Jilin province were in mediate risk. Zhenlai, Tongyu
were in heavy risk. Taobei, Ningjiang, Fuyu were in light risk. The information obtained from interviewing the district official
committees in relation to result compiled was statistically evaluated. The GFDRI was developed to be an easily understandable
tool that can be used to assess and compare the relative risk of grassland fire disaster in different counties in t western
Jilin province, China, and to compare the different relative contributions of various factors, e.g., frequency of grassland
fire and quality of emergency evacuation plan. The GFDRI is specifically intend to support local and national government agencies
of grassland fire disaster management as they (1) make resource allocation decisions; (2) make high-level planning decisions;
and (3) raise public awareness of grassland fire disaster risk, its causes, and ways to manage it. 相似文献

破坏性地震发生后,传统的地面通信网络会受到严重的破坏,甚至会处于瘫痪状态,无法保证前后方应急指挥部之间的数据传输、应急通信、指挥调度等应急需求。为了确保地震应急指挥的顺利开展,需要有一套安全、可靠的通信系统,而我国自主研制的北斗卫星导航系统(BDS)是全球性的卫星导航系统,具有精准定位导航、精密授时、短报文通信等功能,可以在灾害应急指挥中发挥重要作用。因此,从地震现场应急工作的需求出发,在分析各种通信技术的基础上,研究探索一种基于北斗卫星导航系统的地震应急现场通信系统,以满足快速获取灾情信息、精准定位灾区位置、实时传送灾情报告的地震现场应急需求,保障地震现场通信能够畅通无阻,确保应急指挥顺利开展。 相似文献
