【摘要】 场地反应对地震动的影响是地震工程学中最重要的课题之一,一些破坏性大地震的震害资料表明局部场地反应可以大大加剧地面运动和建筑结构的破坏。分析比较了几种常用的利用强震记录来分析场地地震反应的方法,并就国内外研究现状做了总结。在此基础上详细介绍了各种方法的原理、适用性及存在的问题,针对其中的某些问题提出了可能的解决方法。对于场地地震动反应问题的进一步研究具有参考价值。更多还原

【Abstract】 The influence of local site effects on seismic ground motions is one of the most important studies in earthquake engineering.Recently,several destructive earthquakes have demonstrated that the amplification of ground motions and associated damage to structures due to local site conditions are a very important consideration in seismic hazard analysis.In this paper,we summarize the different techniques of estimation on the site effects using strong motion records and introduce the basic principle of each method.Finally,their validities and limitations are discussed.This summary will be useful for further study on analysis of the site effects.更多还原
