The study of stress state of rocks at the base of buildings
The formation of the strength, deformation and physical properties of fine-grained soil are somewhat different from the formation of the same properties in the rock and semi rock. When loading the body around the defect occurs stress concentration that causes growth and dis-gation of cracks. This process leads to the formation of the main crack of rock destruction.It was established experimentally that the temperature of the material (∆t) in the main zone of fracture is controlled by material type and stress state. With increasing rock strength ∆t increases. Under uniaxial tension observed minimum value of ∆t, and under uniaxial compression ∆t naturally increases.
