记录到的强震加速度的傅氏幅值谱基于震级与局部土质、地质条件的经验标定(英文)

EMPIRICAL SCALING OF FOURIER SPECTRUM AMPLITUDES OF RECORDED STRONG EARTHQUAKE ACCELERATIONS IN TERMS OF MAGNITUDE AND LOCAL SOIL AND GEOLOGIC CONDITIONS

本文提供了强震加速度傅氏幅值谱的新的标定方程,用来表征基于土质和地质场地分类参数的局部场地条件。文中表明,土质与地质场地条件两者应同时应用于场地特定幅值谱的估计。

New scaling equations for Fourier amplituds spectra of strong earthquake accelerations are presented for characterization of local site conditions in terms of soil and geologic site classification parameters. It is shown that both soil and geologic site conditions should be used together in estimation of the site specific spectrum amplitudes.
