【摘要】 用2002年3月31日台湾MS7.5地震时上海地区软土地表和基岩记录的加速度资料讨论了地表软土覆盖层面波的地震动反应,并用经验格林函数法合成了台湾未来8级大地震在上海基岩和土层处的面波加速度时程,初步估计了其对高层建筑的影响。其结果对上海的工程抗震设计有参考价值。更多还原

【Abstract】 Using the data of seismic accelaration on both soil surface and rock recorded in Shanghai area in Taiwan M_S7.5 earthquake on March 31,2002,the amplification response of ground motion for S wave on soil coverage is discussed.The acceleration time-history curves of S wave on the rock and soil coverage of Shanghai city in possible future M_S8 earthquakes are composed with empirical Green-function ,and its influnce on high buildings is estimated preliminarily.The result could be useful to aseismic designing of high building in Shanghai.更多还原
