... enhancements in testing procedures and in the interpretation of the results (Jovičić et al., 1996 ; Viana Da Fonseca et al., 2009). However, a direct approach to assess the quality of vibration of BE has not yet been systematised, despite its impact on test results. As cantilever...

...M. C. L. Quinn; C. D. P. Baxter; G. R. Potty Fibre-optic distributed acoustic Sensing (DAS) provide information on vibration response comparable with geophones and seismometers and may become widely used for infrastructure monitoring. DAS can be used to monitor earthquake activity, carbon dioxide...

... no such direct access. All involve measurement of the ground surface vibration as a result of the excitation, whether of the ground or of the buried asset directly. Together, these techniques constitute a substantial step change in the way buried infrastructure can be detected using vibro-acoustic methods...
