Seismic refraction
WebDisadvantage. Advantage. Disadvantage. Refraction observations generally employ fewer source and receiver locations and are thus relatively cheap to acquire. Because many source and receiver locations must be used to produce meaningful images of the Earth's subsurface, reflection seismic observations can be expensive to acquire. WebTherefore, the study would help geotechnical engineers interpret subsurface information based on seismic refraction method data. Therefore, the following question arises: How to establish a relationship between SPT and Seismic Refraction tests, to obtain dynamic parameters in soils of the Palestina Canton?
