在地震动数值模拟方法中,谱元法和有限元法是应用较广泛的两种方法。基于经典的Lamb问题模型,首先推导给出地表竖向位移的解析解答。然后分别利用常用的四阶谱元法和线性有限元法,模拟了地表脉冲力源作用下模型的位移响应。考虑有意义的最短波长内的采样点个数及单元高宽比的变化,对比了两种方法的模拟精度;结果表明:对于谱元法,观测点与波源之间需至少包含两个网格,在此条件下,最短波长内包含一个网格(最短波长内5个...

The spatial autocorrelation (SPAC) method requires a special circular array where several observation points are equally spaced on the circumference. In order to look for the possibility of developpin...
