Abstract: In the present study, a numerical model was established to investigate the influence of the prefabricated cracks of different dimensions on the mechanical properties and damage evolution of irregular sandstone. To this ...

Abstract: Zonal disintegration around a deep excavated tunnel is a characteristic of the rock mass intense fracturing phenomenon. In this paper, three-dimensional numerical tests on the failure processes of rock samples containing ...

Abstract: Joints with different angles in rocks have significant impacts on their fracture mechanisms. In this study, scanning electron microscopy (SEM), energy-dispersive spectrometry (EDS), and microcomputed tomography (Micro-CT) ...
