摘要
以积分本构方程为基础,应用对应原理建立线性粘弹体中的波动方程,采用伪谱法进行数值模拟.实际计算结果表明该方法能有效模拟标准线性粘弹体中地震波的传播.
The article is based on the integal equation, we get the wave equation based on the standard linear viscoelasic solid with the corresponding theory and used the pseudospectral forward data modeling in the wave field. It proves the method could effectively model the sprea of seismic wave in the linear viscoelastic solid by what we theoretically analyze.
