Deep geological disposal is currently the most feasible option for the long-term isolation of radioactive waste, consisting in emplacing the waste into tunnels or drifts excavated at great depths in suitable geological formations. The use of bentonite, a h ...

This paper reports recent advances in modelling MICP at the engineering scale, in particular with respect to the stress-strain-strength modelling of bio-cemented soils. A complete Bio-Chemo-Hydro-Mechanical (BCHM) model is presented. The BCH model is based ...

Deep disposal of high-level radioactive waste is the preferred solution worldwide for the long-term disposal of nuclear waste. This concept involves a series of geological and engineered barriers that provide isolation of the waste from the biosphere. Most ...

This study analyses the response of compacted bentonites upon hydration based on a coupled hydro-mechanical elasto-plastic framework. As an alternative to multi-porosity interpretation, the framework was selected based on the experimental evidence of adsor ...

Despite the increasing understanding of bentonite behaviour, there is still missing evidence on how different hydro-mechanical loadings, including sequences of hydration and compression, affect the fabric and the volume change behaviour of the material. It ...

The FEBEX test was a large-scale demonstration project for the deep geological disposal concept of nuclear waste involving bentonite seals that lasted 18 years. One of the objectives of the test was to evaluate the capabilities of numerical methods to prov ...

The volumetric response of compacted bentonites against environmental actions is a key aspect in most designs of nuclear waste repositories. The safety assessment of such repositories must account for robust and reliable models of stress–strain for bentoni ...

Understanding the mechanical behaviour of compacted bentonite upon re-saturation is of outmost importance in most designs of nuclear waste disposal repositories. The behaviour of bentonite is characterized by its stress-path dependency and it is typically ...

Microbially induced calcite precipitation (MICP) is an innovative biogeochemical ground improvement technology that can be used in-situ to improve soil stiffness and strength, by precipitating calcite within the soil. Bio-chemo-hydro-mechanical processes a ...
