基岩地震动参数与震级和距离的关系
FUNCTIONAL RELATIONS OF BEDROCK MOTION PARAMETERS WITH EARTHQUAKE MAGNITUDE AND DISTANCE
-
摘要: 关于强地震对结构的作用,应当考虑随时间变化的地面运动的全过程。 这个过程的统计特征是由震级、中间介质及地表土层的特性决定的。 因为现在已经有了从基岩运动推算地表运动的可靠方法,所以搞清基岩运动的特征并由此对基岩运动的过程作出估计,显得特别重要。 本文对美国27个基岩台上的强震记录的反应普以及几个最大值与震级和震源距离的关系进行了统计分析,找到它们的关系。从这些关系出发,对指定的震级和震源距离的基岩,可以估计它的运动特征,并人工造成一组运动过程。Abstract: It is not any single maximum value, but the whole process of the ground motion that determines the behavior of a structure during a strong earthquake. Statistical characteristics of the whole process or the time history of ground motion are functions of earthquake magnitude and propagation path and media, especially soil condition near ground surface. Since there exist some potentially reliable method to calculate ground surface motion from bedrock motion, reasonable evaluation of bedrock motion parameters and generation of time histories therefrom seem to become more important.The present paper analysed records obtained on 27 U. S. stations on bedrocks, trying to find out some statistical functional relations of the acceleration response spectra and some maximum values with earthquake magnitude and distance which are the most important basis for generating time history of ground motion.
