Experimental investigations of the soil-concrete interface: physical mechanisms, cyclic mobilisation and behaviour at different temperatures

Lyesse Laloui, Alessio Ferrari, Alice Di Donna

The behaviour of the pile-soil interface is important for the response of floating piles in terms of displacement and lateral friction. Regarding energy piles, which couple the structural roles of deep foundations with the principle of shallow geothermal e ...

Constitutive and numerical modeling of anisotropic quasi-brittle shales

Francesco Parisio

Understanding the hydro-mechanical behavior of shale is fundamental to assess the safety of deep geological nuclear repository sites. Several countries have adopted argillaceous formations as host geological media for the repository. In Switzerland, the ca ...

Global Sensitivity Analysis of Transient Code Output Applied to a Reflood Experiment Model using the TRACE Code

Andreas Pautz, Damar Canggih Wicaksono, Omar Zerkak

Appropriate model assessment requires proper understanding of the impact of variations of model parameters and their interactions on results. However, in many thermal-hydraulic (TH) simulations, the code often predicts time-dependent output where the impac ...

Contribution to the design methodologies of piled raft foundations under combined loadings

Lyesse Laloui

Although simplified methods have been proposed to allow for group effect and soil-pile-raft interaction, most of them are concentrated on one type of loading rendering the applicability of these methods rather limited to cases under such loads. In the case ...

Modeling Soil–Plant Dynamics: Assessing Simulation Accuracy by Comparison with Spatially Distributed Crop Yield Measurements

Sara Bonetti

Coupling hydrological models with plant physiology is crucial to capture the feedback mechanisms occurring within the soil–plant–atmosphere continuum. However, the ability of such models to describe the spatial variability of plant responses to different e ...
