提出通过波场模拟来对比不同的模态解释的正确性,以检验和修正频散曲线的提取。对模拟数据和实测数据的分析表明,该方法进行频散曲线的检验和修正是可靠的,可以有效提高频散数据的质量。
It is proposed to compare the correctness of different modal interpretation by wave field simulation to test and correct the dispersion curve extraction. The analysis of the simulated data and the measured data shows that the method of dispersion curve testing and correction is reliable and can effectively improve the quality of the dispersion data.
