【摘要】：宏观掌握我国建筑物分布和抗震能力现状,震前对政府指导建设规划、建筑物抗震加固和民众提高防灾意识,震时指挥地震应急、损失评估等工作有重要指导意义。该文在对我国各地区建筑物抗震能力开展大量抽样调查的基础上,研究经济、土地利用、设防情况、人口密度和行政区划属性等因素与区域建筑物抗震能力的相关性,建立中国大陆区域建筑物抗震能力综合分区分类方法;利用实际地震震害资料、震害预测资料及建筑物群体震害预测方法,建立不同地区各种结构类型的建筑物地震易损性矩阵;结合不同区域内所具有的各类建筑物存量,基于GIS软件平台,计算并绘制在基本设防烈度地震作用下中国大陆地震灾害风险损失分布图。文中提出一套评估区域建筑物地震灾害风险损失较为完整的思路和方法,可为生命线地震灾害风险损失和人员伤亡分布等研究提供借鉴。
[Abstract]:It is of great significance for the government to guide the construction planning, to strengthen the buildings, to enhance the people's awareness of disaster prevention, to direct the earthquake emergency response and to assess the losses before the earthquake. On the basis of a large number of sample surveys on the seismic capacity of buildings in various regions of China, this paper studies the correlation between economic, land use, fortification, population density and attributes of administrative divisions, and so on, in relation to the aseismic capacity of regional buildings. A comprehensive zoning classification method for seismic capacity of regional buildings in the mainland of China is established, and a method for predicting earthquake damage by using actual earthquake damage data, earthquake damage prediction data and building group earthquake damage prediction method is established. The seismic vulnerability matrix of buildings of various structural types in different areas is established, and the GIS software platform is used to combine the various kinds of building stock in different areas. To calculate and draw the distribution map of earthquake disaster risk loss in China mainland under the action of basic fortified earthquake intensity. In this paper, a set of ideas and methods for evaluating the risk loss of earthquake disaster in regional buildings are put forward, which can be used for reference in the study of the risk loss of lifeline earthquake disaster and the distribution of casualties.
