基础设施地震易损性的评估研究综述

为了加强基础设施系统地震易损性的研究,最大限度减少地震灾害带来的损失,本文通过对基础设施地震易损性研究文献的回顾,分析总结了基础设施地震易损性的相关概念、研究框架与定量评估方法,研究了基础设施地震易损性主要评估方法的适用范围和优缺点。研究结果表明,现有研究集中于对基础设施系统中部分子系统的评估,且地域性强,许多模型和方法无法扩展到其他地区。大部分对基础设施地震易损性的研究还停留在定性层面,易受主观因素影响,需要加强量化和规范化分析。

Review of Infrastructure Seismic Vulnerability Assessment

It is necessary to strengthen the research on the seismic vulnerability of infrastructure systems and minimize the losses caused by earthquakes. The related concepts of seismic vulnerability of infrastructure,the framework of seismic vulnerability research and the quantitative assessment methods were analyzed and summarized through reviewing the literature on seismic vulnerability research of infrastructure. The application scope,advantages and disadvantages of the main assessment methods for seismic vulnerability of infrastructure were compared. It is concluded that existing studies mostly concentrate on the evaluation of some subsystems in the infrastructure,and they are highly regional,in which many models and methods cannot be extended to other regions. Most of the researches on seismic vulnerability of infrastructure are still qualitative. They are also subject to subjective factors and need to be strengthen in quantitative and standardized analysis.
