Summary

In this paper, simulation model of thermophysical properties test have been established and the accuracy of which have been verified by actual test data. Using linear heat source model to process simulation data for the analysis of different factors influences on simulation results. It shows that when using linear heat source model as the regression model for rock-soil thermophysical properties, in order to improve the thermophysical property accuracy identification, test duration should be 72 hours with elimination of the first 12 hours data and ensure a strong turbulent state for the flow velocity in pipes.
