[en] A review is presented of procedures which can be used for the determination in situ of dynamic soil properties at earthquake-compatible strain amplitudes as required for soil--structure interaction studies. The purpose of this review is to document test procedures and concepts and to present the advantages and limitations associated with these methods from both theoretical and practical standpoints. The study involves a review of published literature relevant to the topic and discussions with various individuals from academic, consulting, defense, and governmental organizations with expertise in the fields of wave propagation, testing in situ, and solid mechanics. 258 references, 94 figures, 16 tables
