Comparison among SASW, ReMi and PS-logging techniques: Application to a railway embankment

►Comparison of the accuracy of 3 techniques in identifying a soil profile ►PS-logging is the most accurate technique in identifying a soil profile ►PS-logging estimates higher Vs values than ReMi and SASW ►SASW and ReMi estimate very similar Vs values for the same layer ►The mean deviation of the Vs values obtained by the 3 techniques is around 10-40 m/s
