Description

technical field [0001] The invention relates to a creep experiment device and an experiment method of weak rock and soil materials, in particular to a uniaxial compression creep experiment device and an experiment method of weak rock and soil materials. Background technique [0002] Creep refers to the phenomenon that the material deformation increases with time under the continuous action of constant stress. A large number of on-site measurements and laboratory mechanical experiments have shown that all geotechnical engineering materials have certain creep properties, especially for soft rocks and loose rock masses containing muddy fillings and interlayer fracture zones, the creep properties are more severe. is significant. Even relatively hard rock mass will creep to a considerable extent when the burial depth reaches a certain value and is under high ground stress conditions. Since the creep effect is an important factor affecting the long-term stability of geotechnical...
