It is well known that, even in the same density and water content, alterations in soil structure introduce different soil properties, especially in a range of elastic response. This fact on clayey soils has been confirmed by the extensive studies on their compaction (e.g., Ref. 1) and, recently, that on loose granular materials has been reported by some researchers as a by-product in their liquefaction studies (e.g., Ref. 2). Such detailed discussions have been scarcely made on dense granular materials, however, though unconsciously presented in the scatter of their characterization results. Through the results of repeated load tests on densely compacted specimens of two granular materials, suggested in this study are three aspects of their soil structure: (1) the occurrence of different initial soil structure, (2) the possibility of alterations in soil structure due to the loading, and (3) the existence of a soil structure compatible with the applied stress conditions. The last two aspects are also evidenced by the results of subsequent damping torsion tests using the same dense specimen. Moreover, it is suggested that the resilient, or recoverable, properties determined under the compatible soil structure can be correlated to the stress conditions with a small wide of scatter band. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
