RISFracture and Time-Varying Multifractal Behaviors of Single-Flawed Red Sandstone with Different Wavilness Angles
Publisher: ASCE
Abstract: To study the cracking behaviors and deformation damage process of single-flawed red sandstone with different wavilness angles, a series of uniaxial compression tests are conducted to investigate the effect of wavilness ...
3D Digital Analysis of Cracking Behaviors of Rocks through 3D Reconstruction Model under Triaxial Compression
Publisher: ASCE
Abstract: The cracking behaviors of rocks significantly affect their mechanical properties. In this paper, a digital analysis approach with X-ray Computed Tomography (CT) imagery is developed to investigate the cracking and mechanical ...
Probabilistic Assessment for Slope Using the Generalized Chebyshev Inequalities
Publisher: ASCE
Abstract: This paper aims to estimate the probability of failure (Pf) of slope based on Chebyshev inequalities. Traditionally, for a slope reliability analysis, the supposed distribution types of shear strength parameters are employed; ...
