【摘要】：近年来在西太平洋地区发生的一系列重大自然灾害如地震、飓风等给人类社会敲响了警钟,为了应对重大自然灾害的不利影响,世界各国政府都在研究或已经出台了防灾减灾保险法律如地震保险法加以应对,这应该说是防灾减灾研究的一个必然的趋势。而完善的地震保险政策的出台必须建立在工程结构全寿命期地震损失成本研究的基础上。由于我国目前工程结构全寿命期地震损失成本研究等基础应用研究的缺乏导致我国巨灾保险政策迟迟难以推出,基于此,总结和回顾了工程结构全寿命期地震损失成本研究的理论内涵和研究现状,分析了以往工程结构地震易损性研究和全寿命期地震损失成本研究所面临的理论缺陷和应用局限,重点阐述了基于组合的地震易损性研究的理论优势、具体实施步骤和关键技术特点,最后展望了基于此建立我国工程结构全寿命期地震损失成本研究框架体系的重大意义。
[Abstract]:In recent years, a series of major natural disasters, such as earthquakes and hurricanes, that have occurred in the western Pacific region, have sounded the alarm of human society. In order to cope with the adverse effects of major natural disasters, The governments all over the world are studying or have issued the law of disaster prevention and mitigation insurance, such as earthquake insurance law, which should be said to be an inevitable trend in the study of disaster prevention and mitigation. The perfect policy of earthquake insurance must be based on the study of the cost of earthquake loss in the whole life period of engineering structure. Due to the lack of basic application research such as the study of earthquake loss cost of engineering structures in our country at present, it is difficult to put forward the catastrophe insurance policy in our country. This paper summarizes and reviews the theoretical connotation and present situation of the research on the seismic loss cost of engineering structures in the life cycle, and analyzes the theoretical defects and application limitations faced by the previous researches on seismic vulnerability of engineering structures and the cost of seismic losses in the whole life period of engineering structures. In this paper, the theoretical advantages, concrete implementation steps and key technical characteristics of seismic vulnerability research based on combination are expounded. Finally, the significance of establishing the framework system of earthquake loss cost research for engineering structures in China is prospected.
