摘要

利用现场实测波速和钻孔资料,根据中国建筑抗震设计规范(GB50011-2001)和美国FEMA编制的NEHRP(2000)以及欧洲抗震规范(EUROCODE8,1998)关于场地分类划分的标准,对福州市区典型场地进行了场地类别划分,讨论了划分结果的适用性。文章认为,对福州市区带有软弱夹层土的场地,简单的划分方法可能对长周期地震动估计不足,应当考虑用其他方法估计地震动。
According to the Chinese Seismic Code,recommended provisions of NEHRP of U.S. and Eurocode8,the measured wave velocity and drill data are used to study the site classification for typical soil sites in Fuzhou city,and the applicability of its results is also discussed.It is found that for reclaimed sites with soft layers,simple site classification by these codes underestimates seismic motions of long period.Seismic motions should be estimated by alternative methods.
