The subject matter of this thesis is the study of the
mechanical behavior of clay and residual soils subjected to
a series of tests with temperatures ranging from 20 to 70ºC.
The experimental program consisted of Atterberg limits,
consolidation tests with incremental loading (SIC),
triaxial consolidated undrained tests (CIU) and direct
shear tests on both soil types under saturated conditions.
Samples for Atterberg limit tests have been pre-heated in
oven to the specified temperature. Heating control and
thermal distribution systems have been specially developed
for insuring an homogeneous temperature throughout the
consolidation, triaxial and direct shear tests.
The thermal balance times for the two soils were achieved
by means of a calibration method developed for the heating
system. Transducers and load cell calibration were carefully
calibrated acording to the temperature range for the
testing program.
It may be concluded that pre-heating to temperatures below
70ºC has no influence on
the Atterberg limits results for both soils. Consolidation
tests have shown that heating on
samples leads to an increase in compressibility and also on
the coefficient of consolidation.
From the triaxial tests it was observed that an increase in
temperature leads to an increase in strength and to smaller
excess porepressures during undrained shear tests.
The increase in shear strenght with temperature observed on
triaxial tests was also confirmed by direct shear tests.
These effects were more significant in clay than in residual
soil.
