| Abstract: | This paper introduced the basic principles of 4 indoor testing methods of thermal physical properties of rock and soil, such as hot-wire method, hot plane source method, heat balance method and differential scanning calorimetry (DSC), analyzed advantages, disadvantages and applicable range of each method, pointed out that site drilling and sampling, the choice of instrument parameters during indoor sample preparation and test, and human operation factors all directly affect the reliability of testing results, and then gave relevant suggestions based on work experiences of the authors that national relevant departments and sci-tech agencies should make unified norms for testing methods and instrument products and build up quantity traceability system as soon as possible to ensure the reliability of testing data and improve the comparability of the data from different labs. |
