极罕遇地震在防灾减灾规划中的应用研究——以唐山市建筑抗震易损性分析为例
|
摘要
以唐山市中心城区为例,在分析普遍遭受设防烈度地震下城市建筑抗震能力的基础上,采用情景构建,以唐山市遭受极罕遇地震,分析了唐山市现状建筑在遭遇极罕遇地震下抗震能力。分析结果显示,唐山市现状一般建筑整体上基本满足抗震设防要求。当遭受极罕遇地震时,发生毁坏的建筑比例为33. 84%。设防烈度地震下分析结果较好地反映了唐山市中心城区现状建筑满足国家规定抗震设防能力情况,而极罕遇地震分析结果则反映了唐山市所面临的超越设防烈度地震的风险大小,二者互为补充,对全面认识唐山市中心城区一般建筑抗震能力具有一定现实意义。
Taking the city center of Tangshan city as an example,based on the analysis of the seismic capacity of urban buildings under the earthquake intensity,the reconstruction of the Tangshan earthquake in 1976 was carried out. The present situation of Tangshan city center was analyzed. Earthquake resistance under earthquake. The results show that the general situation of the central city of Tangshan city,the overall construction of the basic to meet the requirements of seismic fortification. When the terrible earthquake,the proportion of buildings that were destroyed was 33. 84%. The results of the analysis of the earthquake in the tunnel are better reflected in the situation of the central city of Tangshan city to meet the national requirements of seismic fortification capacity,and extremely rare earthquake analysis results reflect the Tangshan city center city is facing the risk of exceeding the fortification earthquake intensity. They complement each other,a comprehensive understanding of the central city of Tangshan city,the general building seismic capacity has a certain practical significance.
