PRACTICAL CONSIDERATIONS FOR FIELD GEOPHYSICAL TECHNIQUES USED TO ASSESS GROUND STIFFNESS

This paper concentrates on the practical considerations required to obtain reliable shear wave velocity measurements that can then be used to assess ground stiffness. Three field geophysical techniques are described and typical operational considerations necessary to ensure good data are discussed. Illustrations of the capabilities and shortcomings of each particular method are given by reference to case studies on a range of subsurface conditions including sand, clays and fills of different types. Finally comparisons are made with deformation modulus values derived from other conventional soil tests. (A) For the covering abstract see IRRD 883023.
