Titre : An insight into the water retention properties of compacted clayey soils Type de document : texte imprimé Auteurs : E. Romero, Auteur ; G. Della Vecchia, Auteur ; C. Jommi, Auteur Année de publication : 2011 Article en page(s) : pp. 313–328 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Laboratory tests Suction Partial saturation Fabric/Structure of soils Clays Compaction Index. décimale : 624 Constructions du génie civil et du bâtiment. Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : Experimental data from different testing methodologies on different compacted clayey soils, with dominant bimodal pore size distribution, are presented and analysed, to provide a comprehensive picture of the evolution of the aggregated fabric along hydraulic and mechanical paths. Fabric changes are analysed both from the porous network viewpoint, by means of careful mercury intrusion porosimetry investigation, and from the soil skeleton viewpoint, by quantifying swelling and shrinkage of the aggregates in an environmental scanning electron microscopy study. The consequences of the aggregated fabric evolution on the water retention properties of compacted soils are analysed and discussed. A new model for water retention domain is proposed, which introduces a dependence of the intra-aggregate pore volume on water content. The model succeeds in tracking correctly the evolution of the hydraulic state of the different soils investigated along generalised hydromechanical paths. The proposed approach brings to light coupling between intra-aggregate and inter-aggregate pores in the retention properties of compacted clayey soils. Dependence of the air entry and the air occlusion values on swelling and shrinking of aggregates, besides void ratio, is introduced and discussed.

Ponts et charpentes Résumé : An analytical upper-bound plasticity solution is presented for the calculation of the undrained bearing capacity of strip footings on or near slopes. Typical results, presented in terms of the undrained bearing capacity factor, are shown to be in excellent agreement with finite-element analysis results and generally more conservative than those obtained from other available solutions. The proposed upper-bound solution is used to investigate the influence of the slope angle, the distance of the footing from the slope, the footing width and the soil properties on the undrained bearing capacity.

Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : Earthquakes have damaged harbour structures, both recently and historically. Vivid examples are provided by two recent events: the Kobe earthquake (Ml = 7·2, 1995), involving Kobe port, Port Island, Rokko Island and Fukae Island in Japan; and the Chi-Chi earthquake (Ml = 7·3, 1999), involving Taichung Harbour in Taiwan. The results of surveys of deformation patterns of the ground surface at the two harbours after the events, and the published results of well-planned shaking-table tests, are analysed: the shaking-table tests provided images of the deformed profiles for the submerged backfill of a scaled-down quaywall model. On the basis of these data a simple model is proposed to explain the failure mechanism in large lateral displacements of gravity quaywalls during earthquakes. The results show that the Mononobe–Okabe theory underestimates the resultant of earth pressure from the liquefied submerged backfill. For the cases of the two earthquakes studied in this paper, several dimensionless parameters obtained by using the proposed simple model have similar values.

Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : An investigation into the frequency nonstationarity in the response of primary-secondary (P-S) systems and the impact it could have in the analysis of such structures has been presented in this note. For this purpose, a torsionally coupled P-S system subjected to nonstationary support motion is considered here. Simulated time history records of relative displacement of the secondary system are used to evaluate the time varying power spectral density functions. This is achieved by using a wavelet-based time-frequency analysis, which shows the temporal variations in the frequency content. The numerical results presented in this study advocate the use of nonstationary analysis of the P-S system for their proper design as conventional methods using cascading approximation may fail to capture this phenomenon, especially in the light of tuning and torsional coupling. System parameters such as mass ratio and radius of gyration are also observed to have a significant impact on the time varying frequency content of the response which is evidenced from the constructed time varying power spectrum.

Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : Small timber layers can be mechanically laminated into a larger timber cross section using shear keys to prevent slip between the layers. These mechanically laminated beams are commonly referred to as keyed beams and their use has a strong historical precedence. Current building codes and design standards do not provide adequate guidelines for the analysis of keyed beams. This project examined the applicability of an interlayer slip model to predict the partially composite behavior of the keyed beams. Solutions to the interlayer slip model for common loading configurations were developed, as were stiffness parameters for the semirigid wooden shear keys used to provide composite action. Small and full-scale testing of timber components was also performed to verify the interlayer slip model’s ability to predict the stiffness of specific keyed beam specimens. A comparison of the interlayer slip model to historical keyed beam test data was also conducted. The interlayer stiffness model, as well as the analytical shear key stiffness parameters, was able to accurately predict both the behavior for the full-scale keyed beams tested specifically for this research as well as the historic keyed beam behavior. Shear key configuration, moisture content, and clamping connector stiffness all played significant roles in the actual keyed beam stiffness.
