Abstract
Thermal diffusion process in soils reflects the engineering characteristics of soil components and internal structures. Based on the experimental and numerical observations on dry sand-rock deposits, different soil stratifications or structures can promote the different surface temperature changes by heating the surfaces even with the same heat source. This study suggests a method using the surface temperature changes to estimate the internal structure of the underground. Infrared images taken on the soil surface and thermocouples are used to measure the surface temperature changes with time. The results show that the surface temperature changes can be used as an index property to estimate the thickness of dry soil layer on the bedrock up to about 10cm.
