原始语种摘要: To study the influence of sandstone fissure angle on its characteristics, we performed sandstone uniaxial compression experiments with different prefabricated fissure angles. The infrared radiation temperature (IRT) response characteristics of the prefabricated fissure sandstone and the influences of the fissure angles on mechanical properties, failure modes and infrared radiation indicated the following: (1) the peak stress and failure rate increased as the prefabricated fissure angle increased; the stress peak σ f had a quadratic functional relationship with the prefabricated fissure angle α , and the elastic modulus E was linearly related to the angle of the prefabricated fissure. (2) When 0° ≤ α < 45°, the prefabricated fissure tip formed wing cracks that were nearly...
