地震烈度和地震动参数相关性研究进展及讨论

Research progress and discussion of the correlation between seismic intensity and ground motion parameters

地震烈度直观反映震害轻重程度,而根据地震动记录推测烈度可大大加速烈度评定进程。另外我国目前抗震设计还处于烈度和地震动参数并用时期,需要两者关系,因此研究烈度与地震动参数(峰值加速度/PGA,峰值速度/PGV)的关系十分必要。本文介绍了中外各国两者相关性研究的历史沿革以及研究成果,并进一步对所有研究成果进行了对比分析及讨论。

Seismic intensity directly reflects the severity of damage in the earthquake. It can greatly accelerate the assessment process to predict the intensity according to the ground motion records. In addition,now both intensity and ground motion parameters are used during the seismic design in China,and the correlation between them is needed,therefore the study of the correlation between seismic intensity and peak ground motion parameters（ peak ground acceleration / PGA,peak ground velocity / PGV） is necessary. This paper describes the domestic and abroad historical evolution and research achievements of the correlation between seismic intensity and peak ground motion parameters,and gives a further analysis and discussion of all the research achievements.
