Bridges are one of the road structures that are most exposed to icing, a problem that is widely dealt with through salting, a technique that reduce the lifespan of the bridge. Seasonal storage of solar heat energy captured directly through the asphalt laye ...

Deep geological repository involving a multi-barrier system constitutes one of the most promising options for isolating high-level radioactive waste from the human environment. In order to certify the efficiency of waste isolation it is essential to unders ...

This paper presents an overview of new technologies and applications on thermoactive geostructures. A discussion session on issues involved with near surface geothermal systems is presented, focusing on opportunities for developing new technologies to addr ...

Energy geostructures are foundations equipped with absorber pipes, exchanging heat with the surrounding ground. They provide a good heat source for the heating and cooling of buildings but the temperature variations they undergo bring new challenges. Therm ...

Of the various types of road structures, bridges are the most exposed to icing; the problem of icing is widely addressed through salting, which reduces the lifespan of the bridge. One promising solution to avoid the use of salt is the seasonal storage of s ...

This study addresses the geothermal potential of using the anchors of a cut-and-cover tunnel as heat exchangers with the ground for seasonal heat storage. The influence of the soil properties and water table level were investigated. Various service conditi ...

Energy geostructures represent a renewable and clean source of energy which can be used for heating and cooling of buildings and de-icing of infrastructures. This technology couples the structural role of geostructures with the energy supply, using the pri ...

COupled seismogenic GEohazards in Alpine Regions (COGEAR) is an interdisciplinary natural hazard project investigating the hazard chain induced by earthquakes. It addresses tectonic processes and the related variability of seismicity in space and time, ear ...

The use of concrete geostructures for energy extraction and storage in the ground is an environmentally friendly and easy way of cooling and heating buildings. With such energy geostructures, it is possible to transfer energy from the ground to buildings b ...

A deep geological repository involving a multi-barrier system constitutes one of the most promising options to isolate high-level radioactive waste from the human environment. In order to certify the efficiency of waste isolation, it is essential to unders ...

The mid-term safety of deep geological nuclear waste repositories is based in part on the presence of a buffer, the main role of which is to isolate the environment from radionuclides. A design evaluation of such a repository is necessary to assess the pot ...
