【摘要】 首先,介绍了地震形成的自然因素和非自然因素,并对其发生原因进行了分析和研究;其次,通过对1999-2009年间的地震现场的灾害调查资料和损失评估的资料进行研究,对其进行分析与处理,采取以实际烈度区作为分配单元,建立适用于县级区域小尺度的地震风险分析模型;最后基于烈度的地震分析模型与基于建筑物易损性地震分析模型预测结果进行比较,由此说明在县级区域小尺度上,地震风险分析模型的适用性。更多还原

【Abstract】 We first introduced the earthquake causes which consist of the natural factors and unnatural factors.Second,we use data from the investigation of earthquake disasters and the information of disaster losses 1999-2009,gathering respective sections strength data of the population,the per capita GDP and the area of land,from evaluation information of earthquake disaster and statistics of the earthquake province when the earthquake happens.By analyzing and handling the above data,use virtual broken-level areas as allocation units and establish risk analysis model for medium and small scale earthquake of county.Comparison the two forecast results from the earthquake analysis model based on strength and building damage to prove that the earthquake analysis model based on strength is more suitable for medium and small scale county.Finally,we introduced some knowledge about self-protection when the earthquake happens.更多还原
