Seasonal Heat Transfer and Ground Thermal Response in a Power Transmission Tower Foundation
X. Duan and G.F. Naterer
Seasonal heat transfer in a power transmission tower foundation is analyzed to study the ground thermal response to the tower. A Variable Heating Strength (VHS) model is used to predict the transient ground thermal response and an experimental test cell is designed to measure the seasonal ground temperature variation. Results show that the tower footing induces additional temperature increases in the summer and temperature decreases in the winter. This response varies seasonally and also varies in different positions in the ground.
