Evaluation Study of Boundary and Depth of the Soil Structure for Geotechnical Site Investigation using MASW

This study reviews the correlation between the experimental Rayleigh dispersion curve and the Vp & Vs ground model versus depth. Six samples of stations A , B , C , D , E and F were used in the experiment.The geophone spacing used was set 1 m and total length of each line was 23 m. The result...
