Many offshore geotechnical problems—such as cyclic T-bar penetration and lateral buckling of pipelines—are affected by the tendency of fine-grained soils to strain-soften due to remoulding. Careful calibration of the constitutive model parameters that control strain softening is essential for accurate simulation of these processes. This is usually achieved by matching constitutive model response with standard element test data, which implicitly assumes that homogeneous stress/strain fields exist within the sample. However, popular element test protocols (e.g., triaxial, simple shear) cannot apply sufficient deformation—at least as measured at the boundaries—to achieve fully remoulded conditions. This work explores the potential to determine strain-softening parameters experimentally, directly from image-based full-field deformation measurements and external loading data. Artificial data generated from finite element simulations of biaxial compression and T-bar penetration tests, using a non-locally regularised strain-softening constitutive model based on Modified Cam Clay, are then used to demonstrate the potential of the proposed technique. The results demonstrate significant potential for the application of the technique to identify constitutive parameters from full-field measurements even when polluted with modest measurement noise.

Micropile groups (MPGs) are an effective means of geological disaster prevention for small- and medium-sized landslides, with the advantages of light structures and convenient construction. However, the mechanical and deformation characteristics of MPGs are complex, and their practical application is ahead of theoretical research, which greatly limits the popularization and application of MPGs. This paper conducts a series of centrifuge model tests to investigate the mechanical and deformation characteristics and the antislip mechanism of MPGs, then compare them with those of conventional piles (CPs). In particular, MPGs with and without the platform in the strengthening process of the talus slope are compared, and monitoring the reinforcement effect of MPGs subjected to gravity loading. The results suggest that the soil pressure shows a triangular distribution pattern and is influenced by the position of the potential slip zone and the geometry of the bedrock surface. The compatibility deformation of the pile–soil leads to the stress release of the soil behind the pile, which is an important part affecting the antislip mechanism of the MPG. The platform limits 75% of the pile top displacement of the MPG and simultaneously redistributes the stress of the piles, providing a better overall antislip effect of the pile–soil composite.

Simple numerical methods that allow to obtain stress and strain paths in sand during self-boring pressuremeter tests are presented in this paper. The material is considered to undergo deformation in drained and plane-strain conditions. The flow rules of Rowe, Cambridge-type (Cam clay and Nova) model, and the sawtooth model are used in the analysis. Elastic strains are also considered in relation with the flow rule of Rowe. The proposed approach has been evaluated using a reference pressuremeter test performed on Ticino sand in a calibration chamber. The results indicate that the stress–strain–volume change responses of the sand predicted by the various models are quite similar, with and without consideration of the elastic strain components. Des méthodes numériques simples, qui permettent d’obtenir les cheminements de contraintes et déformations pendant les essais pressiométriques autoforeurs dans le sable, sont présentées dans cet article. Le matériau est considéré être sollicité en conditions drainées et en déformation plane. Les règles d’écoulement plastique utilisées sont celles de Rowe, de type Cambridge (Cam clay et Nova), et le modèle « dents de scie ». L’approche proposée tient aussi compte des déformations élastiques dans le cadre du modèle de Rowe. La méthode a été évaluée à l’aide d’un essai pressiométrique de référence, effectué dans une chambre de calibration, sur le sable de Tessin. Les résultats indiquent que les réponses du sable en termes des relations contraintes – déformations – changements de volume, prédites par les différents modèles, sont assez similaires, avec ou sans la prise en compte des déformations élastiques.

The objective of this paper is to discuss the effect of grain shape and angularity on the undrained behaviour of sands. Four fine to medium (D
50 = 0.15–0.29 mm) and uniform sands were examined. These sands have similar and (or) identical grading curves, but differ with respect to the angularity of their grains. Under the electron scanning microscope two sands have rounded grains and the other two have subangular to angular grains. For sands with rounded grains, evidence of undrained behaviour undergoing systematic weakening (shear stress reduction after a transient peak deviator stress) is provided by torsional hollow cylinder tests. However, sands with the same grading curve and void ratio, but angular grains, show stable response with a continuous increase in strength after a transient peak. A small variation in the sand gradation, i.e., D50 = 0.22 ±0.07 mm, does not appear to alter the pattern of undrained response described earlier, with the angular sand (D50 = 0.15) exhibiting stable response to shear and the rounded sands (D50 = 0.22 and 0.29) having unstable response to shear. The stiffness characteristics of the sands are also presented. Triaxial compression tests were performed to confirm the pattern of response observed under torsional testing. L’objectif de cet article est de discuter de l’effet de la forme et de l’angularité des grains sur le comportement non drainé de sables. Quatre sables de fins à moyens (D50 = 0.15–0.29 mm) et uniformes ont été examinés. Les sables ont des courbes de gradation similaires et (ou) identiques, mais comportent des grains avec des angularités différentes. La microscopie électronique a balayage a révélé que deux sables ont des grains arrondis tandis que les deux autres ont des grains de type sous-angulaires à angulaires. Dans le cas des sables avec des grains arrondis, des essais en torsion en cylindre creux ont permis de constater un affaiblissement systématique du comportement non drainé (réduction de la contrainte en cisaillement après un pic transitoire de la contrainte déviatrice). Cependant, les sables avec la même courbe de gradation et le même indice des vides mais avec des grains angulaires ont démontré un comportement stable avec une augmentation continuelle de la résistance après un pic transitoire. Une faible variation dans la gradation du sable, c’est-à-dire D50 = 0.22 ±0.07 mm, ne semble pas modifier le type de comportement non drainé décrit précédemment; les sables angulaires avec D50 = 0.15 étant stables en cisaillement, tandis que les sables arrondis avec D50 = 0.22 et 0.29 ont un comportement instable en cisaillement. Les caractéristiques de rigidité des sables sont aussi présentées. Des essais de compression triaxiale ont été effectués afin de confirmer les comportements observés sous torsion.

Soil structures are often comprised or supported by soils that are mixtures of cohesive and granular geomaterials. These soils are termed as intermediate or mixed soils and are widely found in natural deposits and man-made soil structures. The objective of this paper is to study the behavior of mixed clayey soils under monotonic, cyclic, and post-cyclic monotonic loading, with the main focus on the last of these three. For this purpose, a number of strain-controlled monotonic, cyclic, and post-cyclic triaxial compression tests were carried out on “clay–sand” and “clay–gravel” mixtures in undrained conditions. The effects of sand (or gravel) contents, number of cycles, cyclic strain amplitude, consolidation pressure, and grain size on the mechanical behavior of the mixtures are evaluated. The major findings from the laboratory study are: (i) the addition of granular materials to the clayey soils increases excess pore-water pressure during strain-controlled monotonic undrained shearing and cyclic loading and (ii) during post-cyclic monotonic shearing, mixed clayey soils behave similarly to overconsolidated soils; the higher the granular material is, the higher the overconsolidation ratio would be. Based on the research results, an algorithm for estimating post-cyclic mechanical parameters of mixed clayey soils, without conducting cyclic and post-cyclic tests, is suggested. Les structures de sol sont souvent composées ou supportées par des sols qui sont des mélanges de géomatériaux cohésifs et granulaires. Ces sols sont nommées intermédiaires ou sols mélangés et sont retrouvés fréquemment dans les dépôts naturels et dans les structures de sol fabriquées. L’objectif de cet article est d’étudier le comportement de sols argileux mélangés soumis à des chargements monotoniques, cycliques et post-cycliques monotoniques, avec l’emphase mise sur ce dernier type de chargement. Pour ce faire, des essais en compression triaxiale monotoniques, cycliques et post-cycliques avec déformation contrôlée ont été effectués sur des mélanges « argile–sable »et « argile–gravier »dans des conditions non-drainées. Les effets sur le comportement mécanique du contenu sable (ou gravier), du nombre de cycles, de l’amplitude de la déformation cyclique, de la pression de consolidation et de la granulométrie ont été évalués. Les principaux résultats de l’étude en laboratoire sont : (i) l’ajout de matériaux granulaires aux sols argileux augmente la pression interstitielle pendant le chargement en cisaillement et cyclique monotonique non-drainé avec déformation contrôlée et (ii) durant le cisaillement monotonique post-cyclique, les sols argileux mélangés se comportent de façon similaire aux sols sur-consolidés; plus il y a de matériaux granulaires, plus élevé sera le ratio de sur-consolidation. Selon les résultats de la recherche, un algorithme qui estime les paramètres mécaniques post-cycliques de sols argileux mélangés est suggéré, sans avoir à effectuer les essais cycliques et post-cycliques.

Concrete face rockfill dams (CFRDs) are considered to be fundamentally safe, especially against leakage, and to be a low-cost alternative at many sites. Their design is based on empirical experiences rather than theory. The present paper describes post-construction deformation and leakage using 27 CFRD case studies. The analysis shows that deformation normal to the face slab is larger than the post-construction crest settlement when the dam height exceeds 100 m and that the long-term leakage rate increases rapidly when the dam height exceeds 125 m. On considère que les barrages en enrochements avec face amont en béton (« CFRD ») possède une sécurité fondamentale, particulièrement contre les fuites et ont été une alternative à bon marché pour plusieurs sites, de plus leur conception est basée sur des expériences empiriques plutôt que sur la théorie. Le présent article décrit la déformation après construction, et les fuites au moyen de 27 études de cas de CFRD. L’analyse montre que la déformation normale à la face de la dalle est plus grande que le tassement de la crête après construction lorsque la hauteur du barrage dépasse 100 m, et le taux de fuites à long terme augmente rapidement lorsque la hauteur du barrage excède 125 m.
