Large test to study the role of soil-air interaction in soil cracking
(The Hong Kong University of Science and Technology (HKUST), 2018)
Text en actes de congrés
Accés obertSoil surfaces in contact with the atmosphere are interfaces where different processes play an important role in triggering the formation of cracks due to desiccation. Empirical evidence shows that variables such as solar ... -
Effects of compaction on desiccation cracking of clayey soils
(The Hong Kong University of Science and Technology (HKUST), 2018)
Text en actes de congrés
Accés obertCracking in desiccating soils is an important topic in soil compacted works. This paper presents an experimental study on the effect of compaction on the cracking of a silty clay soil, which was subjected to drying conditions. ... -
Analysis of the hydration of an unsaturated seal
(American Society of Civil Engineers (ASCE), 2018)
Text en actes de congrés
Accés restringit per política de l'editorialThe paper contains a coupled numerical analysis of the hydration of a potential sealing system for isolating shafts, ramps, and connecting galleries in a deep geological repository for high level nuclear waste. The modeling ... -
Shear strength properties and collapse response of a sandy silt under generalized stress states
(American Society of Civil Engineers (ASCE), 2018)
Text en actes de congrés
Accés restringit per política de l'editorialThe paper presents preliminary results on the shear strength properties and collapse response of a compacted low-density mixture of fine sand and clayey silt in a hollow cylinder apparatus. Shear strength tests at two ... -
Digital twins in civil and environmental engineering classrooms
(International Centre for Numerical Methods in Engineering (CIMNE), 2018)
Text en actes de congrés
Accés obertDigital twins are understood as digital replica of physical models whose behavior can be observed simultaneously (digitally and physically) in real time. These tools are increasingly used in advanced industries for several ... -
Automation and control in a submarine drill rig
(Society for Underwater Technology, 2017)
Text en actes de congrés
Accés obertRemotely operated submarine drills are gaining acceptance as offshore geotechnical investigation tools for they provide a more convenient and often cheaper solution to geotechnical drilling vessels. The MD500 is an underwater ... -
Mechanical and Thermal DEM analyses of baled MSW storage
(International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), 2017)
Text en actes de congrés
Accés restringit per política de l'editorialMunicipal solid waste is sometimes stored in baled form either before or after treatment. General design requirements for MSW landfills, such as slope stability and lining long-term integrity are still relevant for bale ... -
THM analysis of compacted clay liner response to baled municipal waste
(2017)
Text en actes de congrés
Accés restringit per política de l'editorialHeat is generated in municipal waste containment facilities due to the chemical and biochemical evolution of waste. Sometimes it is required to check if the level of heat generated during the deposit lifetime may damage ... -
Periodic cells for large-scale problem initialization
(EDP Sciences, 2017)
Text en actes de congrés
Accés obertIn geotechnical applications the success of the discrete element method (DEM) in simulating fundamental aspects of soil behaviour has increased the interest in applications for direct simulation of engineering scale boundary ... -
Numerical analysis of desiccation, shrinkage and cracking in low plasticity clayey soils
(2017)
Comunicació de congrés
Accés obertThis paper presents a numerical study of the desiccation processes of low-plasticity clayey soils that usually result in shrinkage and often in cracking. For the theoretical development of the numerical model, concepts of ... -
Discrete element modelling of granular column collapse tests with industrial applications
(International Centre for Numerical Methods in Engineering (CIMNE), 2017)
Text en actes de congrés
Accés obertDescribing the behaviour of granular materials is a challenging issue for the industry. Our work concerns packaging industries where packing equipment is designed to handle a wide range of powders and bulk solids with ... -
Flowability of granular materials with industrial applications: an experimental approach
(EPJ Web of Conferences, 2017)
Text en actes de congrés
Accés obertDesigning bulk material handling equipment requires a thorough understanding of the mechanical behaviour of powders and grains. Experimental characterization of granular materials is introduced focusing on flowability. A ...
