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 ...

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 ...

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; ...

Abstract: A novel, meshless numerical method, called general particle dynamics (GPD), is proposed to simulate the initiation, propagation, and coalescence of three-dimensional (3D), pre-existing penetrating and embedded flaws as ...

Abstract: The fluctuation of reservoir water levels has significant impact on bank slope stability near a reservoir. Therefore, it is necessary to analyze the stability of bank slopes with reservoir drawdown. In this paper, a novel ...

Abstract: In this research, a novel meshless numerical method, termed general particle dynamics (GPD), to simulate crack initiation, propagation, and coalescence in rock-like materials subjected to impact loads was developed. In the ...

Abstract: To investigate the roles of nonisometric flaws in rock failure behaviors, uniaxial compression tests with the combined monitoring of acoustic emission (AE) and digital imaging were conducted on sandstone specimens containing ...
