Abstract：Exploitation of the shallow geothermal energy has gradually become a key topic in geotechnical engineering worldwide with the rapid development of renewable energy and geothermal heat pump techniques. However，the theory of the shallow geothermal energy falls far behind its application.In particular，the mechanism of soil under the complex coupling of stressand temperature fields remains unclear.For a single soil such as sand，clay，and silt， some results have been found by carrying out the temperature-controlled experiments and proposing the related thermal constitutive models. To promote more comprehensive and indepth thermal behavior of soil and contribute to more practical application of the thermal constitutive model in energy engineering，this paper firstly summarizes the experimental research on the thermomechanical properties of soil.Then，research progress and status quo of thermomechanical constitutive relations of soil，based on different theoretical frameworks，arereviewed in detail.Thereafter，theapplication of these thermomechanical constitutive relations in engineering practiceis introduced briefly.Finally，suggestions in further research are provided，and the development trendof the thermomechanical constitutive relationshipof soil is discussed and prospected，in view of current existing problems.
