Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
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 ...
Info4Dourou2.0 is a research project aiming at improving agricultural yield and water consumption in drip irrigated areas in semi-arid regions by using continuous soil humidity measurements. Within this framework, the main goal of this thesis was to invest ...
Energy piles efficiency is strongly affected by soil saturation conditions: low water contents considerably decrease their performance thus limiting the possibility to extend their application in arid environments. This paper investigates the MICP (Microbi ...
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 ...
Experimental results of volumetric response of a volcanic soil were collected in standard oedometric tests, with the aim to evaluate the volumetric response of this soil when subjected to loading and wetting paths. Microstructural features of reconstituted ...
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 ...

Soil erosion is an important environmental phenomenon that causes many side effects such as reduction of soil productivity in the fields and transportation of pollutants to non-contaminated areas. Extensive well designed and controlled flume experiments in ...
This study investigates the impact that different magnitudes and combinations of thermal and axial mechanical loads have on the mechanical behaviour of energy piles in saturated sand. The work is based on the results of a series of thermo-hydro-mechanical ...
This paper focuses on the main issues discussed during a session on the impact of thermohydromechanical behavior of soils on thermoactive geotechnical systems, and how they could affect the performance of thermoactive geotechnical systems. Both soil behavi ...
The lack of reliable methods for evaluation of soil abrasivity and revealing the effects of different parameters on wear rate are nowadays considered as a deficiency in geotechnical investigation during feasibility study, design and construction phases of ...
