3-D micro-architecture and mechanical response of soil cemented via microbial-induced calcite precipitation

We introduce the application of microbial-induced calcite precipitation via the ureolytic soil bacterium Sporosarcina Pasteurii in freeze-dried form, as a means of enhancing overall MICP efficiency and reproducibility for geotechnical engineering applicati ...

Modelling landslides in unsaturated slopes subjected to rainfall infiltration using material point method

Lyesse Laloui, Alessio Ferrari, Samila Sanjeevanie Bandara

This paper presents a dynamic fully coupled formulation for saturated and unsaturated soils that undergo large deformations based on material point method. Governing equations are applied to porous material while considering it as a continuum in which the ...

Analysis and estimation of gripper TBM performances in highly fractured and faulted rocks

Federica Sandrone, Jian Zhao, Erika Paltrinieri

This paper focuses on performance analysis of Tunnel Boring Machine (in particular gripper TBMs) in highly jointed rock masses and fault zones. In order to investigate possible relationships between these difficult excavation conditions and TBM performance ...

Evolution of the hydromorphodynamics of mountain river confluences for varying discharge ratios and junction angles

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña, António Heleno Cardoso

Mountain river confluences are characterized by narrow and steep tributaries that supply abundant sediment load to a main channel that, in turn, provides the dominant flow discharge. In addition, bed sediments consist of poorly sorted mixtures that promote ...

G: Fracture energy, friction and dissipation in earthquakes

Marie Estelle Solange Violay

Recent estimates of fracture energy G (') in earthquakes show a power-law dependence with slip u which can be summarized as G (') ae u (a) where a is a positive real slightly larger than one. For cracks with sliding friction, fracture energy can be equated ...

Analysis of TBM tunnelling performance in faulted and highly fractured rocks

Erika Paltrinieri

The thesis focuses on the study of the performance of TBMs in highly jointed and faulted rocks. Despite the great production rates recorded in favourable ground conditions, the TBM advance can be significantly slowed down in limiting geological situations ...

Exploring the physics of sediment transport in non-uniform super-critical ows using a large dataset of particle trajectories

Christophe Ancey, Joris Heyman

In this article, we present 10 experiments carried out in a steep, shallow water ume made of an erodible bed of natural, uniform gravel. We simultaneously recorded bed load particle motion, bed and water elevation using two high-speed cameras. Particle tra ...

Dynamic fracture along bimaterial and heterogeneous interfaces

Fabian Barras

Using a spectral resolution of the elastodynamic boundary integral equations, this poster is presenting the effect of tougher heterogeneities along a planar fracture plane. A centered crack propagating along a 1-D heterogeneous interface under mixed-mode l ...
