Thermohydromechanical behaviour of soils and soil structure interfaces 265

m. Employing a constant value of Young’s modulus with temperature in the analysis
and design of energy geostructures can be considered appropriate:
i. True
ii. False
n. The angle of shear strength of soils under constant volume conditions markedly
varies with temperature:
i. True
ii. False
o. The slope of the critical state line depends on temperature:
i. True
ii. False
p. The primary consolidation coefficient markedly varies with temperature:
i. True
ii. False
q. Define the structure roughness and specify how this parameter can be used to
characterise interfaces as smooth or rough.
r. Smooth interfaces show a higher shear resistance compared to rough interfaces:
i. True
ii. False
s. Smooth interfaces with a soil show a higher shear resistance compared to that of
the soil:
i. True
ii. False
t. Define the main parameters that influence the mechanical response of soil struc-
ture interfaces.
u. Define constant normal stiffness and constant normal load conditions. Which con-
ditions is representative of the state of restraint characterising interfaces between
geostructures and the surrounding ground?
v. Describe the three failure modes that can characterise soil structure interfaces.
w. The shear strength of interfaces between concrete and coarse-grained soils is
highly influenced by temperature variations:
i. True
ii. False
x. The shear strength of interfaces between concrete and fine-grained soils varies
with temperature:
i. True
ii. False
