A seismic survey was carried out to investigate the quality of the rocks under a secondary road with damage. The space for the seismic line was limited by the morphology of the slope.Continue reading “Case study – A road crossing a fault zone”
In this work, seismic refraction tomography (SRT) was performed to investigate the characteristics of the subsoil and to investigate the evidence of the presence of a tunnel used for the carrying of water.
The survey was carried out using 24 vertical geophones and performing a high number of vertical energizations both inside and outside the line, in order to have a good coverage by seismic rays throughout the section.Continue reading “Case study – Detection of a tunnel.”
Following the rupture of an water pipeline, a landslide movement occurred in an area classified as highly susceptible to collapse. The event dislocated a retaining wall and created tension cracks in the ground. In order to define the geometry of the materials involved in the movement, a seismic survey was carried out using the technique of seismic refraction tomography and the MASW.Continue reading “Case study: Evaluation of the depth of the rupture surface of a landslide”
