大同—阳高地震灾害评估及灾因分析

本文记述了大同—阳高地震震害情况,同时对造成灾害的原因进行了分析,认为此次地震震级不大而损失严重的主要原因除了与地震持点和发震构造有关之外,还与当地民舍抗震性能差、施工质量低有直接关系。     

Public participation in NGO-oriented communities for disaster prevention and mitigation (N-CDPM) in the Longmen Shan fault area during the Wenchuan and Lushan earthquake periods

ABSTRACT

The Longmen Shan fault area in southwest China is one of the world’s most active earthquake zones. The epicenters of the two most recent earthquakes, the 2008 Wenchuan earthquake (8.0?Ms) and the 2013 Lushan earthquake (7.0?Ms), both of which caused serious losses, were only 85?km apart. Community-based disaster risk reduction is the foundation of the disaster management system pyramid and is critical to the success of ‘sustainable hazard mitigation’. Based on multiple collaborative stakeholder perspectives, this paper examines public participation in an NGO-oriented Community for Disaster Prevention and Mitigation (N-CDPM) in the period between the two earthquakes as a multi-stage problem; N-CDPM establishment, normal operations, disaster testing, and continuous improvement. Multi-stage field research was conducted in the affected areas in the Longmen Shan fault area to examine the collaboration in each stage, after which the differences were compared across the four stages based on eight key indices; scales, core stakeholders, core network stability, mean number of lines, mean collaborative level, governments, and individual and public organization participation. The government participation, individual participation, and public organization participation are then discussed. This paper provides a novel research approach to CDPM in multiple earthquake regions and gives rich insights into the collaboration between the government and the public for N-CDPM.     

分布式防震减灾系统的初步设计

阐述了以分布式地理信息系统(DGIS)软件为开发平台的分布式防震减灾系统的初步设计和系统建设的目的、原则,讨论了系统的软硬件配置,结合某系统实例阐明了分布式防震减灾系统的框架结构以及模块功能组成.指出分布式网络GIS的应用研究已经成为防震减灾系统建设的一个重要发展方向.该思路正在结合具体的城市实施,探索为防震减灾系统的建设提供新的经验.     

基于两阶段模糊熵权的震灾抢修抢建价值评估模型

面对地震对工程的破坏与抢修抢建需求,提出一种两阶段模糊熵权的抢修抢建工程价值评估模型。探究地震作用下抢修抢建工程价值特征体系的参数、变化趋势等特征,给出工程项目价值指标的混合判断矩阵,集成模糊熵权方法对工程项目价值指标阶段、准则阶段进行层次化评估,确定工程项目的抢修抢建相对价值系数。模型应用于震后抢修抢建案例,得到工程项目隐含的权值信息,据此得到抢修抢建案例的价值系数及执行序列。     

清代闽台地区自然灾害及其救治办法研究

清朝,闽台已经成为自然灾害的多发地区,常见的灾害有洪水、干旱、台风、地震与瘟疫等.对福建危害最大的是水灾,对台湾危害最大的则是风灾.两岸人民为抗击自然灾害而共同努力,清地方政府采取多项救灾措施如蠲免、赈粮、捐赀及赋予台湾官员独断财权以应付突发灾情等,并取得了一定成效.     

地铁地基液化变形的影响因素研究

研究了一些对地铁隧道抗震稳定有较大影响的因素。例如,地铁隧道的整体平均容重和地铁隧道的埋深,尽管它们对地基的孔隙水压力发展影响不大,但却对地铁隧道的震后残余变形影响相当显著。还有,砂性土中粘性土的含量多少对砂性土的动力行为有直接而显著的影响。最后,从能量的角度分析了输入不同地震波的地铁地基土层动力反应的差异。     

自然灾害灾后重建技术及实践的研究进展

灾后重建是在灾害体发生之时及发生之后,采取应急救援、灾害管理,以及灾后评估、救助、规划等一系列过程,是一个典型的系统工程,可划分为前期应急重建、中期恢复重建及后期发展重建3部分。以自然灾害为主要研究对象,在分析中外关于灾后重建文献的基础之上,归纳了灾后重建的系统特征,介绍了灾后重建技术和实践的研究进展。灾后重建技术包括灾害分类分级、应急救援、灾后评估、灾害管理和重建规划5个方面,灾后重建实践研究分为地震、飓风、洪水和海啸4个方面,并对中外的灾后重建研究发展进行了展望。     

The effect of different educational interventions on schoolchildren's knowledge of earthquake protective behaviour in Israel

Knowledge of appropriate behaviour during an earthquake is crucial for prevention of injury and loss of life. The Israeli Home Front Command conducts a yearly earthquake education programme in all Israeli schools, using three types of educational interventions: lectures, drills and a combination of the two. The aim of this study was to evaluate the effectiveness of these interventions in providing students with knowledge. We distributed a questionnaire to 2,648 children from the 5th and 6th grades in 120 schools nationwide. Knowledge scores for both 5th and 6th grades were increased, regardless of type of intervention, compared to the non-exposure group. A combined intervention of lectures and drills resulted in the highest knowledge scores. Our findings suggest that for the age group studied a combination of lectures and drills will likely prepare students best for how to behave in the event of an earthquake.     

青海玉树7.1级地震震害特点分析及启示

根据2010年4月14日玉树7.1级地震震害现场调查资料,对其震害特点进行了全面的分析总结,阐述了震区环境及其地质构造背景,对断层效应及场地效应等也进行了分析,并归纳总结了防震减灾的经验与启示。     

重大自然灾害后遗体处置应急预案研究

重大自然灾害发生后一般都会伴随着大量人员的遇难,及时妥善处置灾后众多遇难者遗体,是许多国家面临的棘手问题。借鉴我国唐山7.8级地震和汶川8.0级地震中遗体应急处置的经验与教训,从遗体的搜集、存放、运输、消毒、防腐、保存、火化、掩埋等方面,探索遗体处理应急预案的程序与内容,从而提高政府应对重大自然灾害后大量遗体的应急处置能力,全面保障灾区群众的身心健康。
