【摘要】 为满足重要工程对设计地震动的需要,文中研究了一种考虑场地附近天然地震记录数据相位非平稳特性、同时拟合S0A(T)、PGA和PGV的人造地震动技术,并以新疆玛纳斯县城区基岩场地为例,利用该区域强震记录提取的天然地震动非平稳相位,进行了非平稳人造地震动的合成。研究成果可为拟合反应谱人造地震动的工程应用提供参考。更多还原

【Abstract】 In order to meet the requirement of important projects for designing ground motions,a new artificial ground motion technology is researched for considering non-stationary phase from near site earthquake records and to fit compatible S0(T),PGA and PGV are fitted with the non-stationary phase,simultaneously.This new technology is applied for generating the non-stationary artificial ground motion at the rock site of Manas Town,Xinjiang,which the non-stationary phase of natural ground motion is obtained from the strong motion records of the region.The results can supply an example and foundation for the engineering application of artificial ground motion fitting response-spectrum.更多还原
