The processing result notes that the method of time frequency analysis may improve stability and liability of extracting Rayleigh wave velocity.
处理结果表明,应用时频分析方法可以提高瑞雷波速提取的稳定性和可靠性。
Spatial autocorrelation method; Phase velocity dispersion of Rayleigh wave; Circular array; Microtremor survey method.
空间自相关法;瑞雷波相速度频散;圆形排列;微震勘探法。
Using the latter, with the correlativity of soil 'density and the velocity of the Rayleigh surface wave, we can obtain the compaction of the subgrade.
后者则是用已得到的各层瑞雷波速度值,利用土密度与瑞雷波速的相关关系计算各层的压实度。
