Abstract: Various mechanical responses of rocks under a complex stress state have attracted the attention of engineers. A hollow cylinder torsional apparatus (HCA) was constructed using the discrete element method (DEM). A series ...

Abstract: Methane and other gases released from soft sediments are among the main sources of greenhouse gases in the atmosphere. In this paper, a growth model for isolated bubbles in the sediments was established based on the theory ...

Abstract: An unstable rock mass is a common geological hazard in water conservancy and hydropower engineering in southwest China. The mechanical properties of a rock mass joint and the internal and external physical environment are ...

Abstract: This paper studies soil-erosion problem around cracked sewer pipes, which is usually associated with groundwater infiltration in sewer systems. Four factors (soil-particle size, defect size, water head, and soil height) ...

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 ...
