【摘要】 城市群是经济快速发展的产物。已有的震例表明城市群震害比单个城市的震害更为复杂、严重,对社会的影响更为巨大。阐述了珠江三角洲城市群的发展现状及其地震活动性,分析了城市群的地震灾害特点,并利用现有的震害评估模型及基础数据对珠江三角洲城市群进行震害损失模拟,结果证明城市群震害损失较非城市群更严重,并提出了防御城市群地震灾害的措施。更多还原

【Abstract】 Urban agglomeration is the product of rapid economic development.Past earthquake cases show that seismic disaster in urban agglomeration region was more complex and severe than that in one single city and had more influence on the society.In this paper,the characteristics of earthquake disaster in urban agglomeration,development and seismic activity of Pearl River Delta are analyzed.Using the existing model and basic data,the earthquake disaster is estimated for Pearl River Delta region.The result also proved that the seismic disaster in urban agglomeration region is more complex and severe than that in one city.Finally,the disaster relieving measures are put forward for urban agglomeration.更多还原
