The migration of gases is crucial to ensure the long-term feasibility argillaceous formations for deep disposal radioactive waste. This paper presents an experimental investigation with a multi-scale perspective on response gas transport initially saturated Boom Clay (Belgium). Gas injection tests have been performed under oedometer conditions at different controlled-volume rates, constant tota...

Abstract Over the last decades, numerical modelling has gained practical importance in geotechnical engineering as a valuable tool for predicting problems. An accurate prediction of ground deformation is achieved if models that account pre-failure behaviour soil are used. In this paper, laboratory results consolidated drain (CD) triaxial compression tests and one-dimensional consolidation marin...

Land subsidence is an important environmental problem in the North China Plain (NCP). A typical area mainly located on adjoining areas of Beijing and Hebei provinces was selected to study consolidation characteristics deep clayey soil. Clay samples were collected from 14 boreholes at different depths, compression behavior soil analyzed by high-pressure oedometer tests. Results show that deforma...

Abstract Background Consolidation of clays could be a very time-consuming procedure. However, preloading can increase the speed consolidation; applying an electric field accelerate this procedure significantly. The efficiency electroosmosis approach has been studied for different types previously. At same time, there is no information about performance EO method Tabriz gray clay. Methods This p...

Abstract In the geological disposal of high-level radioactive waste in argillaceous rocks, studying barrier integrity after gas transport and pathway closure thanks to self-sealing capacity is a crucial aspect for safety assessment. This paper presents experimental research Boom Clay (a potential host rock Belgium) evaluate effectiveness possible fissure reactivation during second invasion even...
