A different approach and result to the measurement of K o of granular soils / M. L. Talesnick in Géotechnique, Vol. 62 N° 11 (Novembre 2012) 

Public ISBD [article]  in Géotechnique > Vol. 62 N° 11 (Novembre 2012) . - pp. 1041 –1045 Titre : A different approach and result to the measurement of K o of granular soils Type de document : texte imprimé Auteurs : M. L. Talesnick, Auteur Année de publication : 2012 Article en page(s) : pp. 1041 –1045 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Laboratory  tests  Earth  pressure Résumé : An in-soil version of the null soil pressure measurement system has been used in the measurement of lateral earth pressures of granular soils for at-rest K o conditions. Four uniformly graded soils were tested, from particle diameter 0·15 mm through to 15 mm. Two significant observations were made based upon the data presented. For initial loading, the coefficient of lateral earth pressure, K o, was found to be higher for soil placed in a dense packing arrangement in comparison to that measured for the same soil placed in a loose packing arrangement. The development of horizontal pressure during unloading and reloading was found to be very similar to that of initial loading.

Earth pressure measurements on buried HDPE pipe / M. L. Talesnick in Géotechnique, Vol. 61 N° 9 (Septembre 2011) 

Public ISBD [article]  in Géotechnique > Vol. 61 N° 9 (Septembre 2011) . - pp. 721-732 Titre : Earth pressure measurements on buried HDPE pipe Type de document : texte imprimé Auteurs : M. L. Talesnick, Auteur ; H.-W. Xia, Auteur ; I. D. Moore, Auteur Année de publication : 2011 Article en page(s) : pp. 721-732 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Full-scale  tests  Soil–structure  interaction  Theoretical  analysis  Sands Index. décimale : 624 Constructions du génie civil et du bâtiment. Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : An understanding of the stress distributions that act on buried pipes plays a key role in the development and use of design methods for these structures. The radial stresses that develop on buried flexible pipes have been investigated by a number of researchers through experimental, analytical and numerical methods. However, direct measurements of soil contact stresses acting on small-diameter pipes have not been possible, since commercial earth pressure cells are large, and the stiffness of the cell relative to the soil material is known to influence the measured stresses. A new technique is described for measuring the radial contact stresses acting on buried pipes, and experimental studies are reported that demonstrate the effectiveness of this new technique for measuring contact pressures for both loose and compacted sand backfills. Comparison of the measurements with computations from elastic soil–pipe interaction theory reveals significant discrepancies in the magnitude and distribution of radial pressure around the circumference of the pipe for both loose and compacted backfill conditions. The new measurement technology provides direct support for pressure distributions inferred in earlier studies from measurements of circumferential strains around the pipe circumference.
