. Considering thermal effects in soil leads to the introduction of a new variable, the temperature. Thermal behaviour interacts with hydraulic and mechanical behaviour (thermal-hydraulic-mechanical coupling (THM)). The coupling between these phenomena is complicated and the degree of coupling between one behaviour to another varies . It is the aim of the paper to investigate the application of thermal analyses in the 2D finite element software PLAXIS. To achieve this, a case study which includes modelling of a large-scale test, was performed and the obtained results were compared to the measurements. The aim of the test was to study the influence of the temperature change of concrete on the properties of a clayey silt soil. A concrete block and a layer of clayey silt were placed in a 7.5 m^3 thermally insulated container. Thermoelements were used to measure the air temperature and the temperature inside the concrete block and the soil layer. To model the test, several finite element models were created with varying geometries and boundary conditions. The case study showed that it is possible to predict the temperature distribution in soil due to the curing of a concrete body. However, the obtained results also indicated that further investigations concerning the temperature input and thermal parameters is required to improve the agreement of the computed results with the measurements.
