Detection of buried wooden trestles using Rayleigh-waves
This paper presents results from multi-channel analysis surface waves tests (MASW)conducted on an earth embankment to detect the location of rotten buried tresdes in two different sections (A and B).In Section A,the locations of the trestles are known as well as the soil properties;thus,this section is used for calibration purposes.In Section B,the trestle locations are unknown.A seismic array of 24 geophones with a geophone spacing of 0.5 m is used.Different signal processing techniques were used for the analysis of surface waves to compute dispersion curves,power spectral density functions,distance-frequency contour plot,and wavelet transforms.The results show that MASW tests were able to detect the location of buried trestles.
