摘要: Abstract Prediction of cracking is greatly important when evaluating the stability and safety underground engineering projects. In this paper, 3D-printed samples with a single non-straight fissure are uniaxially compressed, effects inclination angle effective curvature on observed. A simplified approach proposed for determination tip non-tip fissure. The accuracy prediction validated by uniaxial tests. results show that behavior fissures different from straight respect to occurrence cracking. Moreover, significantly influenced geometric parameters addition, can be utilized predict acceptable accuracy.
