“…Practically, temperature generally does not have a significant effect on the engineering properties of most soils; generally, the critical state parameter M is independent of temperature (McCartney et al, 2013a). However, the expansion of water in soils during heating will cause excess porewater pressures to develop, which will result in a decrease in the effective stress.…”

Energy geostructures are structure or infrastructure foundations used as heat exchangers as part of a ground source heat pump system. While piles remain the most common type of energy geostructure, increasingly infrastructure projects are considering the use of other buried structures such as retaining walls and tunnels for heat exchange. To design and plan for construction of such systems, site investigations must provide appropriate information to derive analysis input parameters. This paper presents a review of what information regarding the ground, and also the structures themselves, would be required for the ground energy system design process. Appropriate site investigation methods for energy gesotructures are reviewed, from desk study stages through in situ testing to laboratory testing of samples recovered. Available methods are described and critically appraised and guidance for practical application is given.

TERRE project: interplay between unsaturated soil mechanics and low-carbon geotechnical engineering

et al. 2020

View full text Add to dashboard Cite

The geotechnical construction industry is a major component of the overall construction sector and is strategically important in infrastructure development (transportation, flood and landslide protection, building foundations, waste disposal). Although industry and research in the overall construction sector have been investing significantly in recent years to produce innovative low-carbon technologies, little innovation has been created in geotechnical construction industry, which is lagging behind other construction industry sectors. This paper discusses the interplay between low-carbon geotechnical engineering and unsaturated soil mechanics based on the research carried out within the project TERRE (Marie Skłodowska-Curie Innovative Training Networks funded by the European Commission, 2015-2019,H2020-MSCA-ITN-2015-675762).
