高层建筑承受纵向地震波时的安全核算构想

高层建筑可预期的灾变非至一端，这里仅探讨高层建筑的抗震性能问题。地震过程中楼体受到的是地震波和自身固有频率的共同作用，此时楼体是一个多维动态系统，其应力状态比传统方法所描述的力学模型要复杂行多。本文应用ANSYS三维仿真有限元软件，采用单点响应谱的方法，对楼体在纵向地震波作用下的应力状态和变形情况进行了分析。对楼体构件单元型式的选择、网格密度的确定、有限元模型的建立等也提出了自己的见解。在后处理中，用列表和图形的方式显示了楼体的位移和应用状态。     

天祝地震危险区划研究

研究天祝地震危险区划是一个综合性的课题。通过研究基本查清了自治县的地震危险家底,并进行了分析研究,得出了今后预防地震和主要防震减灾以及地震监测预报等方面的实施意见。揭示了本县的地域异常规律,划分了重点地震危险区。可见研究天祝地震危险区划分和强震预测、预报是很有意义的。

陕京二线输气管道工程场地区域地壳活动性与地质灾害

陕京二线是继陕京一线之后陕西天然气进京的又一条长输管道。管线横贯陕西、山西、河北三省,直到北京市,全长约851 km。该工程对调整沿线各省市的燃料结构与产业结构,进一步改善首都北京的大气环境质量,为 2008年北京成功举办“绿色、环保奥运”,具有深远的意义。陕京二线大部分线路区域地震地质构造十分复杂,地质灾害类型多样,对管道工程和人民生命财产安全潜在危害严重,查明线路的工程地质条件和各类地质灾害,并采取相应治理措施,对于管道顺利建设和安全营运十分重要。

地震应急救援后勤保障质量评价体系的探讨

建立科学的地震应急救援后勤服务质量评价体系，客观评价地震应救援急后勤保障服务水平，是规范管理地震应急救援后勤保障质量的重要手段。本文提出在进行地震应急救援后勤保障质量评价时，调查项目必须根据地震现场后勤工作的需求特点合理设计，取样大小、统计方法必须科学规范。     

The Pyrenees earthquake of 1660: Effects in France

Until 1975 or so, scientists' knowledge of the major earthquake of 1660 in the Pyrenees (in Bigorre) was largely restricted to the meagre information repeated in the classical catalogues. Useful material published in local learned journals was mostly unknown, and has only been unearthed and interpreted since 1976, when two year's work of analysis was started for the "Projet Sismo-tectonique" in France. During and since that project, further routine work necessary for the revision of the historical seismicity of France, has brought to light a new wealth of information from archive sources. This new knowledge, at least from the French side, is used as the basis for a brief macroseismic review of the event north of the Pyrenees, putting forward proposals for the isoseismal lines. Emphasis is placed on the number and quality of the sources, some of which are quoted for evidence of major rockfalls in the meizoseismal region and the wide extent of the felt area, as far north as Salnt-Maixent in Poitou.     

现阶段我国地震应急技术框架分析及评价

破坏性地震发生后,快速高效地开展地震应急工作离不开地震应急技术的基础支撑。为进一步掌握我国地震应急技术现状,持续增强我国应急能力,通过梳理现阶段我国地震应急指挥、地震烈度调查与损失评估、地震现场流动监测3大技术系统,从技术构成、技术功能、存在问题等方面探讨我国现有地震应急技术。结果表明:现阶段我国的地震应急技术发展显著,但仍存在不足和薄弱环节,标准化、智能化、综合化或将成为新方向。     

浅析西吉县党家岔震湖形成原因及其对社会生活影响

现存于宁夏回族自治区固原市西吉县内、以党家岔震湖为代表的43个串珠状堰塞湖是由1920年海原大地震诱发而成。试图从土壤地貌、地形地势和水文河流三个方面对西吉县党家岔震湖形成原因予以分析,借此探究引发地震堰湖所必要的自然条件因素;另外结合史实情况,以居住方式、精神文化和经济发展三个角度来进一步揭示震湖"由无到有"这一自然环境变迁过程对当地社会生活所产生的影响,进而有益于对相关区域未来发展前景给予指导。     

Development of urban planning guidelines for improving emergency response capacities in seismic areas of Iran

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.
