【摘要】：随着我国强震动观测数据数量和质量的大幅提高,破坏性地震发生后所观测到的强震动记录也在试验性地转化为仪器烈度数据.本文将强震动记录引入应急性的生命损失快速评估,借助已有的地震应急灾害损失快速评估模型的表达方法,提出了一种将仪器烈度概率密度函数和生命损失函数相结合的地震人员伤亡快速评估方法.通过确定仪器烈度的概率密度,并结合四川地区已有房屋建筑易损性研究成果,建立了考虑建筑地震易损性并与烈度相关的地震生命损失快速评估函数,并利用汶川地震的强震动记录对本文提出的生命损失快速评估方法进行评估计算.结果表明,该方法的计算结果与实际震害损失结果颇为一致,说明了该方法的可行性,因而能够及时为地震应急救援提供可靠信息.
[Abstract]:With the increase of the quantity and quality of strong motion observation data in China, The strong motion records observed after the destructive earthquakes are also converted into the instrument intensity data on an experimental basis. In this paper, the strong motion records are introduced into the rapid assessment of life loss due to acute events. With the help of the existing rapid assessment model of earthquake emergency disaster loss, This paper presents a rapid method for evaluating earthquake casualties by combining the probability density function of instrument intensity with the function of life loss. By determining the probability density of instrument intensity and combining with the research results of vulnerability of buildings in Sichuan area, this paper presents a new method to evaluate the vulnerability of buildings in Sichuan Province. The fast evaluation function of earthquake life loss considering the vulnerability of building earthquake and the correlation of earthquake intensity is established, and the rapid assessment method of life loss proposed in this paper is calculated by using the strong motion records of Wenchuan earthquake. The results show that, The calculated results of this method are in good agreement with the results of actual earthquake damage loss, which shows the feasibility of the method, and thus can provide reliable information for earthquake emergency rescue in time.
