In-situ Measument of Dynamic Properties of Soils by Steady-state Vibration Technique

This Paper reports the use of steady-state vibration technique in in-situ measurement of Rayliegh wave velocity, within certain exciting frequency range, in saturated cohesive soils at Gaoqiao District, Shanghai.This paper also reviews factors affecting wave velocity, with computed values of shear wave velocity, dynamic shear and elastic moduli etc.
