Compressional Wave Velocity

Last updated: May 31, 2019

What Does Compressional Wave Velocity Mean?

Compressional wave velocity is a measure of the velocity with which sound waves pass through soil and rock strata. It varies with porosity, lithology, degree of fracturing and bulk density of the earth material. Site investigation for trenchless construction includes both soil and rock depending on geology, and the degree of saturation greatly influences the compressional wave velocity.

Different methods such as suspension logging, seismic refraction, crosshole test, and downhole test are used to measure compressional wave velocity.

Trenchlesspedia Explains Compressional Wave Velocity

悬架测井在一个大于200英尺的深度的单个孔中提供剪切和压缩波速度测量。它为解析薄层提供高分辨率为20厘米,可以影响表面响应。它不受土壤岩土界面附近的路径效应或陡峭浸渍床的影响,并针对土壤和软岩进行了优化,提供了更好的渗透和准确的结果。十字孔测试在表面(上百米)附近进行,并确定材料的压缩和剪切波速度。

The downhole test measures the travel time from the time of wave generation until observed by a receiver and predicts the velocity propagation required by elastic waves i.e. compressional and shear wave to propagate through the soil under consideration.
