“…The changes in pore water pressure in the heating and shearing process could lead to the decrease in Su. This subject is consistent with the results of previous study (Campanella and Mitchell 1968;De Bruyn and Thimus 1996;Yu et al 2018) conducted on saturated clay.…”

Unconfined compressive strength (Su) is one of the soil engineering parameters used in geotechnical designs. Due to the temperature changes caused by some human activities, it is important to study the changes in Su at different temperatures. For this purpose, kaolin, illite and montmorillonite clays with a liquid limit (LL) of 47, 80 and 119 respectively, were tested in a temperature-controlled cell in temperature range of 20 to 60 ℃. The results showed that the pore water pressure is a function of temperature and by heating, pore water pressure in the samples increased. In all three types of clay, the Su decreased linearly with increasing temperature. The reduction of Su in kaolin is more than illite and in illite is more than montmorillonite. The reason for this reduction, might be due the difference in the mineralogy of the clays. The results of unconfined compressive tests at different temperatures were simulated using hypoplastic model.

“…In contrast with the result of soft Bangkok clay, 30-40 % reduction in shear strength of Boom clay by raising temperature from 20 to 80°C is reported in [68] using triaxial undrained shear test. Failure envelope of Boom clay in pʹ-q plane and slope of critical state line (M) was also studied and, similar to result of Cekerevac and Laloui [52], the independency of M with temperature change was seen.…”

“…Nevertheless, totally at the end of heating, decrease in cohesion was observed. In contrast, Boom clay exhibited rather different behavior and sharp decrease in cohesion by temperature raise from 20 to 80°C is reported [68]. It worth to note the difference between testing apparatus and material as well as temperature range for these results.…”

“…Yavari et al [39] studied the effect of temperature on friction angles of clay using temperature-controlled direct shear test apparatus and reported that friction angle is mostly independent of temperature. Another recent study for temperature effect on shearing parameters is the work of Yu et al [68] on Boom clay using modified triaxial test. Similar to previous studies, no dependency of friction angle with temperature and clear trend were reported.…”

“…Similar to previous studies, no dependency of friction angle with temperature and clear trend were reported. Yavari et al [39] and Yu et al [68] also studied the effect of temperature change on cohesion of clayey soils. Both decrease and increase are observed in [39] by temperature raise from 5 to 40°C in Kaolin clay.…”

Temperature change in soils and its possible effects date back to 20th century where temperature difference between laboratory and field for sampling made researchers interested in this topic. Due to development of technology and industry nowadays, new engineering applications such as nuclear waste disposal, oil extraction and pipelines, geothermal structures etc. have turned temperature change in soils to one of the high trending research topics where suitable knowledge of thermal effects on soils is required. For this purpose, it is tried at first to highlight the importance of temperature effect on geotechnical design by some examples and possible effect of temperature change on mechanical properties of fine soils are reviewed afterward. Investigation on results from literature proved that temperature change could alter some strength and consolidation parameters of fine soils. Different factors are proposed to be responsible for such thermally induced changes in mechanical parameters, however, existing explanations and comments from literature are diverse and not fully understood yet. In order to fill this gap, it is tried to find connections between different mechanical parameters and their behavior toward temperature change and possibly find a unified approach and factor to explain the mechanism responsible for thermally induced changes in mechanical parameters of fine soils. Finally, at the end, it is concluded that effect of temperature on structural rearrangement of solid particles could be a promising factor to connect the responses of different mechanical parameters toward temperature change.
