摘　　要：为保证国土范围内建筑倒塌风险的一致性,提出了基于目标风险的地震区划图。该图通过求取地震危险性曲线与结构易损性曲线的卷积的风险积分方法计算目标风险。本文介绍了采用风险积分法确定基于目标风险的地震动参数的基本原理,回顾了这项技术在国内外研究与应用的最新进展。此外,还讨论了基于目标风险的地震区划图未来的发展及可能面临的问题。To ensure the consistency of building collapse risk within the country,a risktargeted seismic zoning map is proposed.The risk integral method calculates the target risk by the convolution of the seismic hazard curve and the structural vulnerability curve.Currently,the use of risk-targeted seismic zoning maps has been widely used in practice in the United States,and related studies have been conducted in France,Romania,Canada,Indonesia,Europe and China.This article introduces the basic principles of using the risk integral method to determine the risk-targeted ground motion parameters and reviews the recent progress of research and application of this technique in China and abroad.In addition,we discuss the future development of risk-targeted seismic zoning maps and some of the problems may face.
