Essais sur la conductivité thermique souterraine : analyse contrôlée du site.

Ground thermal conductivity testing: controlled site analysis.


A preliminary study was performed to determine the effects of test duration, power quality, and borehole retesting on in situ thermal conductivity testing. A series of controlled experiments was conducted to investigate these issues. The paper first demonstrates the need for accurate thermal property values and then briefly describes the experimental test apparatus and test site. The results indicate that test duration does significantly affect conductivity test values and that test durations of at least 48 hours are necessary. Other parameters influencing the accuracy of the measurements (heat transfer rate, interval between two measurements, etc.) were investigated.
