EVALUATION OF IN SITU EFFECTIVE SHEAR MODULUS FROM DISPERSION MEASUREMENTS. DISCUSSION

This is a discussion of a paper of the above title by C. Vrettos and B. Prange published in Vol 116, No. 10, October 1990 issue of this Journal. Discusser Gazetas notes that while the procedure for the soil profiles described in the paper is valid, a more cumbersone iterative numerical inversion scheme would be necessary for deposits consisting of several different soil layers, as in the spectral analysis of surface waves method. Gazetas describes a numerical study of the dispersion relations of Rayleigh waves in a deep soil stratum with S-wave velocity increasing with depth. Discusser Rix describes a superior approach to inverting surface-wave-dispersion data using an inversion program based on wave-propagation theory in a layered half-space. The discussions are followed by a closure by the authors.
