摘要
选择了福州盆地二类场地和三类场地内不同土层厚度的10个钻孔,根据福州市地震危险性分析结果,用三角级数迭加法合成50年超越概率10%的基岩地震动3条,将其调幅后输入上述10个代表性钻孔中,得到不同峰值输入下、不同土层厚度土层的反应谱放大倍数(土层地表反应谱除以基岩地表反应谱)。
10 representative bore-holes are selected in 2nd and 3rd category fields in Fuzhou basin,according to seismic risk analysis result in Fuzhou basin,3 rock earthquake waves with their exceedance probability of 10% in 50 years are got with the method of trigonometric superposition,through attenuation,they are input into 10 representative bore-holes,response spectrum enlargement factors（soil surface spectrum divided by rock surface spectrum）under different wave peaks,different soil layer thickness are got.
