Field Measurements on Geothermal Foundations Conference Paper uri icon

  • 2018 American Society of Civil Engineers (ASCE). All rights reserved. The geothermal foundation application expansion into use of large building projects depends greatly on the thorough understanding of its possible effects on foundation. This paper presents the field measurements of a mini-scale geothermal foundation system under Texas A&M University's liberal arts and humanities (LAAH) building including the construction phases, the new thermal cone test (TCT) and the measurements of temperature propagation in both pile and soil. The new in-situ testing method, TCT provides an effective way of measuring the soil's thermal conductivity and specific heat capacity. The temperature measurements of the LAAH building in both pile and soil. These measurements show the heat front propagation in pile and soil during the cooling and heating mode operation. The phrase "heating" and "cooling" throughout this paper refers to the heating and cooling operational mode of the geothermal system to heat and cool the building and not the temperature in the soil.
