Abstract: A beam-element-based rock bolt model is proposed in this paper. The proposed model can not only simulate the compression and tension deformations of bolts in the rock block but also capture the interaction between the bolt ...

Abstract: The Zhala hydropower station plant was under the threat of rockfalls induced from a high slope, especially in rainy seasons. This paper proposes an innovative protection structure consisting of a pervious concrete wall and ...

Abstract: Sand cushions for passive protection structures could reduce the damage that is induced by rockfall impact. Therefore, evaluation of the peak impact force generated by rockfall on the sand cushion is significant to the ...

Abstract: Fracture-dominated flow in fractured rocks is of interest in many areas of scientific and technical research. In contrast to the continuum approach, this study employed a discrete fracture model method to analyze water ...

Abstract: The shear response of rock joints under bolt reinforcement is important for supporting the design of a jointed rock mass. This paper aims to investigate the shear behavior of bolted rock joints with different roughness. ...

Abstract: The asperity morphology has profound influences on the failure characteristics and shear strength of rock joints. To investigate these influences, degradation characteristics and mechanical properties were studied based ...

Abstract: In water-rich rock masses from underground excavations, the flow pressure and confining pressure significantly affect the seepage properties of the fractured rock induced by complex stress. To understand the seepage mechanism ...
