τ-P变换在面波勘探中的应用OA北大核心CSTPCD
Application of τ-P Transformation in Surface Wave Exploration
在介绍了不同类型的地震波在X-T以及τ-P域中的波场特征及辨识方法的基础上,通过数值模拟及工程实例,比较分析面波τ-P变换滤波前后的记录、频谱、频散曲线表明,利用τ-P变换对干扰波进行压制,突出基阶面波,能进一步提高拾取频散曲线的准确性和精度,使反演成果更加可靠.
The wave field characteristics and identification methods of different types of seismic waves in X-T domain and τ-P domain are firstly described,and then the records,spectrums and dispersion curves of surface wave before and after τ-P transformation wave filtering are compared based on numerical simulation and engineering examples.The results show that the noise suppression by using τ-P transformation to highlight fundamental mode can improve the accuracy an…查看全部>>
