A full-scale experimental site with four energy test piles was built on the campus of the Swiss Federal Institute of Technology in Lausanne, Switzerland. This site was used to investigate interaction effects within a group of energy piles. First, the groun ...

In this paper, lightning electromagnetic fields in the presence of an ocean-land mixed propagation path having different configurations are evaluated using a finite-element-based full-wave approach. The simulations are conducted considering lightning strik ...

Turbulences in liquids caused by jets can be of interest for numerous applications. For one, it concerns flood spillway structures within civil engineering but also is key in any area where turbulent mixing is present. The numerical simulations of jets tha ...
Rockfall propagation areas can be determined using a simple geometric rule known as shadow angle or energy line method based on a simple Coulomb frictional model implemented in the CONEFALL computer program. Runout zones are estimated from a digital terrai ...
Filling materials may exist in all scales of rock fractures, not only influencing seismic wave attenuation, but controlling rock mass instability. The objective of this study is to experimentally investigate the seismic response of rock fractures filled wi ...
The effect of the temperature dependence of the internal friction angle is studied in a boundary value problem simulating the impact of a cylindrical heat source on the soil mass in which it is embedded. This follows a previous study which shows that such ...
Variability of the internal friction angle with temperature is studied in a boundary value problem numerically simulating the impact of a cylindrical heat source on the stress and strain in soil mass in which it is emplaced. Even if the thermal increase of ...

Four gravel unconstrained flow experiments were modelled with the DAN-3D and RASH-3D codes. Both the codes, based on continuum mechanics, were developed for the propagation of rapid landslides, like rock avalanches. The codes were at first run to back-calc ...
Thermal variability of the coefficient of the critical state, or the angle of internal friction is examined in view of experimental results obtained for clays and hard rocks. This sensitivity has several implications for the evolution of what is considered ...

Suitable developments of sustainable energy sources are drawn by analysing the Energy sector, considering environmental, economic and social aspects. The particular example of Switzerland is detailed with a focus on the energy consumption in the buildings. ...
