Development of a One-Dimensional Heating Soil Test Cell

ABSTRACT
Coupled thermo-hydro-mechanical (THM) processes are of great importance to geothermal, hydrology, and geotechnical engineering applications. There is a lack of laboratory testing apparatuses to measure the THM processes under controlled true 1-D heating conditions. This paper develops a modified 1-D heat soil cell for the study of THM processes. This soil cell consists of a double acrylic test column and a heating plate at the bottom plate to control the temperature gradient. The test cells are equipped with thermocouples to monitor the temperature changes during heating processes. Two tests are conducted with the boundary temperatures at 50 and 70°C, respectively. Test results show nearly linear axial and radial temperature profiles in the inner soil column. The temperature profiles for the outer soil column are also obtained, showing a significant influence of room temperature on the outer column. The time to reach steady-state temperature for both tests is the same, which is 6 h. A infrared camera was also used to visualize the temperature distribution of the column top surface.
