| Abstract: | Based on summarizing the models that are commonly used to determine underground thermal conductivity,a new simplified cylindrical source model was derived with simplified G-function.A numerical program was compiled for the simplified cylindrical source model,incorporating the parameter estimation technique.The validation of this model was verified by comparing the result with that of a common cylindrical source model from the literatures.It is proved that the simplified model is feasible and available(<5%).It can keep a good precision of calculation. |
