Determination of the Dynamic Material Properties of Soils from the Results of Static Shear Tests

摘要

This report reviews the applicability of several recently developed elasto-plastic and endo-chronic constitutive theories for predicting dynamic soil behavior with parameters determined from static shear tests. Based on this review, a simple procedure for predicting equivalent linear shear modulus and the fraction of critical damping from the results of triaxial compression tests with an unload-reload cycle is developed. The applicability of this procedure is demonstrated on two different soils--Crystal Silica sand and San Francisco Bay mud. Result show the procedure may be useful for preliminary analysis and in situations where more sophisticated testing apparatus are not available.
