vti介质弹性波波场分解的空间域算法
Keywords: vti介质,多分量,空间域,波场分解,克里斯托弗尔方程
Abstract:
？本文在波数域波场分解方法的基础上,研究了vti介质中弹性波波场准纵波、准横波分解的空间域算法。通过求解克里斯托弗尔方程,得到准纵波与准横波的偏振方向及波数域波场分解算子,对其进行反傅里叶变换得到空间域波场分解算子;由空间域波场分解算子与原始波场的褶积即可得到对应不同波型的具有多分量特征的波场分解结果。由于在不同空间位置处采用不同的分解算子,故本文算法能适应各向异性参数随空间位置变化的情况。分别采用均匀vti介质模型、层状vti介质模型和sigbee2avti模型进行了模拟试算,模拟结果验证了算法的有效性。
