对NORESS台阵和ARCESS台阵以及这些台阵内的三分量子台,应用统一的慢度分析方法得出下面的结果:(1)对同一个源区事件的三分量解有相对大的散射;(2)不同的三分量台有不同的解。有证据表明,用统一的半空间模型从三分量数据中不足以推出慢度解,也就是说,地壳和上地幔的分层模型影响了长周期地表响应,地表地形和近地表结构干扰了地表质点运动和慢度解,尤其是在短周期频段。采用新提出的多道散射方法的数值模拟评估了地形影响。理论结果能解释三分量解中观测到的大约一半的异常。另一方面,根据垂直分量的相位延迟得到的台阵解是相对稳定的,因为非几何相位扰动是可以忽略的。
For the NORESS array and the ARCESS array and the three-component quantum stations in these arrays, a uniform slowness analysis method is used to obtain the following results: (1) Relatively large scattering is obtained for the three-component solution of the same source region event ; (2) different three-component platform has a different solution. There is evidence that using a uniform half-space model is not sufficient for deriving slow solutions from three-component data, that is, the layered model of the crust and the upper mantle affects long-period surface responses that interfere with the surface of the Earth’s surface Particle motion and slow resolution, especially in the short-period band. Topographic effects were evaluated using the numerical simulation of the newly proposed multichannel scattering method. The theoretical result can explain about half the anomalies observed in the three-component solution. On the other hand, the solution of the array based on the phase delay of the vertical component is relatively stable because non-geometric phase perturbations are negligible.
