Geoelectrical tomography can be considered the principal method in geo-electrical measurements. This technique combines recent techniques of data acquisition with accomplishment interpretation solutions. The data acquisition […]
Geoelectrical profiling is used when we necessity to study superficial depth ground properties but on long distances. It is applied in defining soil contamination, defining depth […]
Downhole Seismic Testing This technique measures vertical changes in seismic velocity by placing a source at the top of a borehole and measuring travel-times at multiple […]
Knowledge about rocks characteristics beyond the excavation face of tunnels or beneath the bottom hole of a well has always been part of underground engineering and […]
Different techniques (except HVSR method) generally acquire and analyze surface waves in different ways. However, the ultimate aim of the diverse techniques is to determine the […]
For the evaluation of the physical and mechanical characteristics of the rocks an analysis of the seismic data in terms of anelastic attenuation is performed. Factors […]
Hybrid seismic technic is a geophysical survey that combines information obtained from seismic refraction and seismic reflection methods. In particular, the velocity model obtained through seismic […]
Seismic reflection method is a geophysical analysis of the subsoil that allows to accurately detect the stratigraphic and structural configuration of the rock formations underlying the […]
Seismic refraction is a geophysical technique used to explore the subsoil. In practice it is observed that, elastic waves generated artificially from the surface, propagate within […]
