The natural rock mass stress-state at the MH vicinity was studied using the unloading deformation measurements at the small experimental cameras of the 2.5 × 2.5 m2 cross-section.
The paper describes the main parameters and features determining the behaviour of the ground surrounding an underground excavation, namely: (1) the ground conditions (rock mass, stresses and water) and (2) the project related features, (size and shape of the opening and excavation method).
The simulated processes included heat transfer, liquid and vapor water movements, rock-mass stress and displacement, and stress-induced changes in fracture permeability.
Therefore, nanofilms have been utilized as a sensing material in pressure, flow, thermal, gas, optical, mass, position, stress, strain, chemical, and biological sensors.
Mice heterozygous for Errβ deletion have increased fat mass and stress hormone secretion after restraint stress, while those homozygous for Errβ deletion have decreased fat mass and secrete higher baseline levels of stress hormones.
And the high concentration of muscle mass puts stress on the body, as if the lifter were obese.
At each load step, FF-HEDM data were collected to track the crystallographic orientation, center of mass, and stress tensor changes of nearly 1000 grains in the probed volume.
Apart from this, creation of underground opening within stressed rock mass modifies their stress state [6, 7].
The cross section (HSC, HSC with steel liners, UHP-FRC) is varied parametrically to study its effect on mass, principal stresses, damage distribution, and plastic deformation.
