Design of jet-grouting for tunnel waterproofing
(CRC Press/Balkema, 2012)
Text en actes de congrés
Accés restringit per política de l'editorialA case history in Barcelona is described where a tunnel was excavated by traditional methods below an active railway line through a formation with lenses of water-bearing granular material. To avoid the possibility of ... -
Discrete element models of soil-geogrid interaction
(Springer Nature, 2019)
Capítol de llibre
Accés obertGeogrids are the geosynthetics of choice for soil reinforcement applications. To evaluate the efficiency of geogrid reinforcement, several methods are used including field tests, laboratory tests and numerical modeling. ... -
Discussion of “Stresses developed around displacement piles penetration in sand” by Z. X. Yang, R. J. Jardine, B. T. Zhu, and S. Rimoy
(2015-03)
Article
Accés obertThe authors deserve praise for gathering together many different strands of evidence that clarify the mechanics of pile penetration in sand. In their review of numerical approaches to the problem, they correctly indicate, ... -
Effects of heating and hydraulic cycling on the stiffness response of a rigid ansiotropic clay: preliminary results
(2009)
Comunicació de congrés
Accés obertThe poster presents the results of an experimental investigation aimed at evaluating the effects of heating and hydraulic cycling on the small-strain stiffness of a rigid Jurassic clay (Opalinus clay, Jura Mountains, Mont ... -
Effects of tailings viscosity on liquefaction triggering analyses
(University of Alberta, 2021)
Text en actes de congrés
Accés restringit per política de l'editorialRecent analyses have suggested that creep or rate effects may be present in some tailings and can play a role in triggering liquefaction failure. However, the role of creep in liquefaction triggering analysis of tailing ... -
Energy balance analyses during Standard Penetration Tests in a virtual calibration chamber
(Elsevier, 2021-05)
Article
Accés obertThe Standard Penetration Test (SPT) is the most popular example of dynamic probing, a large category of soil testing techniques. Understanding and interpretation of these tests is hampered by the difficulties of reproducing ... -
Engineering assessment of jet-grouted structures
(IOS Press, 2009)
Text en actes de congrés
Accés restringit per política de l'editorialThe treatment characteristics, quality control measures and outcomes of two different jet-grout based soil treatments are described in detail. In the first one, a jet-grouted slab was built to limit retaining wall movements ... -
Enhanced cone penetration test interpretation with the Particle Finite Element Method (PFEM)
(International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), 2019)
Text en actes de congrés
Accés obertThe paper presents an enhanced interpretation of the cone penetration test based on numerical analysis performed using the Particle Finite Element Method (PFEM). This method allows the incorporation of strong non-linearities, ... -

Evaluation of net thrust and torque on mixed-face EPB drives
(2015)
Text en actes de congrés
Accés restringit per política de l'editorialIn this communication we propose a way to estimate net thrust and torque applied at the excavation front by cutting tools from EPB machines when they are working in mixed faces constituted by soils and soft rock. The ... -
Evaluation of self-combustion risk in tire derived aggregate fills
(2011-09)
Article
Accés restringit per política de l'editorialLightweight tire derived aggregate (TDA) fills are a proven recycling outlet for waste tires, requiring relatively low cost waste processing and being competitively priced against other lightweight fill alternatives. However ... -
