Tunnels Résumé : Large-scale one-dimensional compression tests were performed in order to analyze the influence of gravel on the compression properties of gravel-mixed decomposed granite soils. After adjusting the gravel contents of the said soil, specimens compacted at a certain level of compaction energy and water content were tested. Based on the test results, it was observed that when gravel-mixed decomposed granite soil was compacted at the same energy level, there existed a specific gravel content at which the dry density was maximum and which also produced the minimum compression index. Furthermore, an expression based on two-phase mixture theory was proposed to quantitatively evaluate the effects of gravel content through a material parameter calculated using the theory, and the estimated compression curves agreed very well with the results of the experiments.

Influence of water on the compression behavior of decomposed granite soil / Tae-Gew Ham in Journal of geotechnical and geoenvironmental engineering, Vol. 136 N° 5 (Mai 2010) 

Public ISBD [article]  in Journal of geotechnical and geoenvironmental engineering > Vol. 136 N° 5 (Mai 2010) . - pp.697-705 Titre : Influence of water on the compression behavior of decomposed granite soil Type de document : texte imprimé Auteurs : Tae-Gew Ham, Auteur ; Yukio Nakata, Auteur ; Rolando Orense, Auteur Année de publication : 2010 Article en page(s) : pp.697-705 Note générale : Géotechnique Langues : Anglais (eng) Mots-clés : Weathering  Water  Crushing  Compression  Granular  material Index. décimale : 624.1 Infrastructures.Ouvrages en terre. Fondations. Tunnels Résumé : In order to investigate the influence of water on compression characteristics of decomposed granite soils, single-particle crushing and one-dimensional compression tests were carried out on three types of decomposed granite soils as well as on quartz-rich silica sand under both dry and wet conditions. Results showed that the initial crushing strength of a single particle was reduced and strength variability increased due to the weakening effects induced by the presence of water. Moreover, it was observed that the one-dimensional compression behavior of decomposed granite soil was related to the initial crushing strength. Finally, the magnitude of initial crushing strength was also affected by the degree of weathering of the soil.
