“…The tested material is an illitic soil named Arginotech® that contains 77% illite, 10% kaolinite, 12% calcite and traces of quartz and feldspar according to the furnisher. Minipenetration tests, conducted on this soil by Eslami et al (2015) showed the sensitivity of this material to temperature variations. The particle-size distribution of the soil was determined using a laser Malvern Mastersizer 2000® device (Figure 1a).…”

“…The calculation of the bearing capacity of deep foundations is actually based on pressuremeter or/and penetrometer test results (AFNOR, 2012). Eslami et al (2015) studied the effect of temperature variation on penetration test parameters in two compacted soils. However, no data are available on the effect of temperature on pressuremeter parameters.…”

The incorporation of heat exchangers in geostructures produces a cyclic variation of the temperature in the adjacent soil. Therefore, there are important questions about the effect of temperature variations on hydro-mechanical soil parameters. In this study, mini-pressuremeter tests were conducted in laboratory on a homogeneous material submitted to different thermal loading (1 to 40 °C). The tested material, an illitic soil, is compacted in a thermo-regulated container with 0.6 m diameter and 0.8 m height, at optimal water content (31.3 %) and 90% of maximum dry density (1.29 Mg/m 3). Only six tests are performed in each container to prevent edge effects and the influence between the tests. The impact of temperature variation on creep pressure (pf), limit pressure (pl) and pressuremeter modulus (Ep) were determined. A decrease in creep pressure and limit pressure with increasing temperature was observed, while the variation of pressuremeter modulus was less pronounced. The first cycle induced more important parameter variations than the subsequent cycles.

“…Illite is a non-swelling clay found in various proportions in soils due to the illitization of several minerals (Lynch, 1997). Mini-penetration tests, conducted on this soil by Eslami et al (2015) showed the sensitivity of this material to temperature variations.…”

“…Calculation of the bearing capacity of deep foundations are currently based on pressuremeter or/and penetrometer test results (AFNOR, 2000(AFNOR, , 1996Standard ASTM, 1999, 1995. Eslami et al (2015) studied the effect of temperature variation on penetration test parameters in two compacted soils but there is still no available data on the effect of temperature on the pressuremeter parameters. Thus, herein and for the first time, a mini-pressuremeter test adapted to laboratory conditions is used to quantify the temperature effect on the mechanical behavior of the soil.…”

The incorporation of heat exchangers into geostructures leads to changes in the temperature of the adjacent soil. Important issues arise about the effect of temperature variations on hydro-mechanical soil behaviour. The objective of this paper is to improve the understanding and the quantification of the impact of temperature variation on the bearing capacity of thermo-active piles. Currently, the design of the deep foundations is based on the results of in situ penetrometer or pressuremeter tests while there is no published data on the effect of temperature on in situ tests results allowing to specifically assess thermo-active piles behaviour. Herein, an experimental device is developed to carry out mini-pressuremeter tests under controlled laboratory conditions. Mini-pressuremeter tests are performed on an illitic soil in a thermoregulated metric scale container subjected to a range of temperature from 1 to 40 °C. The results showed a slight decrease in the pressuremeter modulus (Ep) and a significant decrease in the creep pressure (pf) and the limit pressure (pl) as the temperature 2 increased. The results showed also the reversibility of this effect during a heatingcooling cycle through the investigated temperature range, while the effect of a coolingheating cycle was only partially reversible. In the case of several thermal cycles, the effect of the first cycle proved to be decisive on the soil parameters.

“…As described in section 1, the thermal conductivity is primarily controlled by the soil texture and structure, defined by soil nature, density, porosity, water content and aggregate size distribution. According to some authors, the maximum thermal conductivity is reached at the optimum moisture content [12,44] and depends on soil microstructure [45]. The thermal conductivity is therefore significantly impacted by the initial compaction level.…”
