Modelling of fiber-reinforced concrete and application case
(International Centre for Numerical Methods in Engineering (CIMNE), 2019)
Conference report
Open AccessThis report summarizes the first results of 2D and 3D finite element method numerical modelling analysis of fiber-reinforced concrete behaviour and a tunnel case study application. A porosity strength-dependant material ... -
Bentonite strain due to cyclic suction changes
(The Hong Kong University of Science and Technology (HKUST), 2018)
Conference lecture
Open AccessA series of suction-controlled oedometer tests were performed on a highly compacted bentonite following drying/wetting and wetting/drying paths from the initial hygroscopic conditions (about 120 MPa) under low vertical ... -
Hydro-mechanical modelling of an unsaturated seal structure
(CRC Press, 2018)
Conference report
Restricted access - publisher's policyThe 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 modelling ... -
Gas effect on CPTu and dissipation test carried out on natural soft-soil of Barcelona Port
(CRC Press, 2018)
Conference report
Restricted access - publisher's policyThere is abundant evidence that gas is present in the sediments of the prodelta of the Llobregat River in the area of the Barcelona Port. The presence of gas has been directly observed by gas releases and deflagrations ... -
Permeability estimates from CPTu: a numerical study
(CRC Press, 2018)
Conference report
Restricted access - publisher's policyRealistic numerical simulations of CPTu in soft soils are now becoming possible thanks to methods like the Particle Finite Element Method (PFEM). They may be used to systematically explore the traditional methods of CPTu ... -
Modeling of gas transport through bentonite taking into account subscale structures with process-dependent behaviour
(2018)
Conference report
Restricted access - publisher's policyIn many nuclear waste disposal concepts bentonite is used as a buffer material forming the near-field around the HLW canisters and the sealing material for the backfilled repository structures. The safety functions of the ... -
Classifying granular materials for feeding performance using experimental and numerical techniques
(2018)
Conference report
Restricted access - publisher's policyFlowability of powders and bulk solids is critical for the packaging industry in the selection and design of bulk material handling equipment. Nowadays, a variety of feeder systems are used for dosing operations in bagging ... -
On the hydration of unsaturated barriers for high-level nuclear waste disposal
(The Hong Kong University of Science and Technology (HKUST), 2018)
Conference report
Open AccessThe paper addresses the topic of the effects of hydration and temperature on the final state of an engineered barrier composed of compacted bentonite. In particular the distributions of water content and dry density are ... -
Stabilization of clayey soil using fibre reinforcement
(The Hong Kong University of Science and Technology (HKUST), 2018)
Conference report
Open AccessThe paper presents experimental and numerical investigations on crack evolution during desiccation, on unsaturated, compacted and reinforced clay using natural Alfa fibres. The effect of fibre content is investigated and ... -
Ice formation in unsaturated frozen soils
(The Hong Kong University of Science and Technology (HKUST), 2018)
Conference report
Open AccessThis paper presents a procedure for determining unfrozen water saturation in a partially saturated frozen soil (clayey silt) using bulk electrical conductivity (EC) measurements. A modification of Archie’s law is proposed ... -
Hygroscopicity issues in powder and grain technology
(The Hong Kong University of Science and Technology (HKUST), 2018)
Conference report
Open AccessThe effect of hygroscopicity on flowability of powders and bulk solids with applications in the packaging industry is experimentally and numerically investigated. Firstly, four granular materials are tested at different ... -
Inclusion of chemical effect in a fully coupled THM finite element code
(The Hong Kong University of Science and Technology (HKUST), 2018)
Conference lecture
Open AccessBentonite-rich clays can be used as a buffer / backfill material in deep geological repositories for nuclear waste. The prediction of the long-term performance of a buffer / backfill in such a complex environment, where ...
