Thermisch-hydraulische Simulationen zur Optimierung von Vereisungsmaßnahmen im Tunnelbau unter Einfluss einer Grundwasserströmung
The ground freezing method has recently been given a boost as a versatile technique to provide artificially frozen ground as impervious and bearing support structures for tunneling applications. Excavation can proceed safely inside the frozen ground structure until the final lining provides …

Air-ground temperature exchange
… the exchange of temperature between the air and ground surface remains constant. However, secular changes in boundary-layer factors can generate anomalous ground temperatures. This dissertation is an investigation of factors that cause separation of air and ground temperatures on a seasonal to …

Experimental investigation of soil volume changes during freezing and thawing
… behaviour of soils during freezing and thawing, with focus on frost heave and thaw settlement. Ground freezing is a natural phenomenon that affects civil engineering projects, especially in cold regions or where artificial ground freezing (AGF) is employed. Freezing causes …

The Du Toitskloof Tunnel project : the construction of the (south) soft ground tunnel, Western Cape, South Africa
… on the excavation and construction of the soft ground tunnel, by means of artificial ground freezing for ground support and stabilisation. The soft ground section of the tunnel being situated at the Western portal, and forming approximately 168 metres of the four kilometre main tunnel. The …

Modelling and Experimental Characterization of Solar-Assisted Ground Source Heat Pump Systems with and without Thermal Energy Storage for Cold Climates
… and reduce building carbon footprint, the use of ground source heat pumps (GSHPs) is gaining traction as a cost-competitive, reliable, and environmentally friendly solution. However, in cold climates, like Canada, heating loads are significantly greater than cooling loads, which makes the amount …
