Web30. júl 2024 · 5.4: Seismic Reflection (Single Layer) Reflection surveys follow the same basic principles as refraction surveys, except of course they use reflected waves instead of refracted waves. We can use reflected waves to get h and v 1, but we cannot get v 2 unless we have a reflection from a deeper layer. WebSeismic Refraction. Seismic refraction is one of the more commonly used seismic methods and has many applications. In geotechnical engineering and mining applications, we have used this technique to determine depth …
