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 seepage characteristics of fractured rock mass under compression and shear are one of the important factors affecting the stability of rock mass engineering. In order to understand the effect of shear action on the ...

Abstract: The aim of this study was to investigate the optimization of cut-blasting methods for deep rock masses under high in situ stress. Several plane fluid–structure interaction (FSI) models were established, and the blasting ...

Abstract: In rock masses, there might be structural nonstationarity in the joint morphology that influences the shear behavior of rock joints. However, research into this effect is seldom reported. In this study, shear tests on ...

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 ...

Abstract: Natural loess with large voids and weakly bonded structures is widespread in the arid areas of the world, particularly northwestern China. Recent experimental studies have shown that the mechanical behavior of natural loess ...
