Detecting Soil Inclusion Inside Piles in the Laboratory Using DTS Method

CODEN: JTEVAB

Abstract

In order to standardize and promote the distributed temperature sensor instrument applied in the detection of pile with soil, model piles with a 0.6 m height and 0.8 m diameter were designed in which the ratio of concrete to clay mass is 2:1, 1:1, 1:2, also including pure concrete pile and clay pile model for comparison. Because of the effect of the clay in the pile to the pile thermal conductivity, the temperature change of the pile was monitored. The change of piles' thermal conductivity, the relationship between temperature and heating power, temperature and piles' materials, and temperature and clay content, were quantitatively studied. Experimental results showed that the temperature linearly increases with the increasing of heating power, but with the increase of clay content, temperature gradient increased; for different piles' material, there are obvious differences regarding the coefficient of temperature and heating power, but with increasing of the clay content increased.
