The influence of the site condition on the seismic response is a fundamental subject in engineering seismology and has been studied for a long historical period 场地条件对地震动的影响研究是一个研究历史较长而又十分重要的地震工程研究课题。
Furthermore , the author study the character of the earthquake factor through researching into historical earthquakes of the investigated area and engineering seismology , it insures the reliability of reverse calculation parameters 此外,本文还着重从历史地震统计及工程地震学的理论研究出发,分析地震参数的取值,从而保证了反演参数的可信度。
