Abstract:
Spectral Analysis of Surface Waves (SASW) is a new seismic method with a potential of being a tool for aiding the geotechnical research in many directions. The technique is an addition to the repertoire of non destructive techniques and has evolved the need to develop realistic and cost effective methods for site characterization. Shear wave velocity is the end result of the method which is used for the study.
The study presented makes use of these methods in the Indian geotechnical engineering research scenario towards the characterization of sites. The scope of study is rather wide, even though a beginning has been made and the results are promising of a future.
The SASW technique has to be assembled from the available literature and then invoked upon, to get the shear wave velocity, as the "signature" of the chosen site. The scope of the work thus encompasses the broad domain of site characterization vis a vis shear wave velocity, which is to be assessed in-situ. Finally the results have been checked using Standard Penetration Test (SPT) results.
