... characteristics of the rock specimens with different initial rack types and water content combinations are studied, and the sensitivity of crack types and water content to the mechanical properties of free face rock is also analyzed. The specimens with typical failure characteristics are selected for microscopic...

... Abstract Tunnel-type anchorage are increasingly used in the construction of long-span suspension bridges. Numerical methods are a major means to study their bearing characteristics and failure modes. The current mainstream research method is still based on continuum mechanics, which cannot...

... studied, and the lost circulation mechanism and main influencing factors of deep shale gas formations in the Changning well area were clarified. The results of the study show that deep shale lost circulations in the Changning well block is prominent and widely distributed longitudinally and horizontally...

... Abstract The primary fractures in rocks have an important influence on the rock breaking efficiency. In order to understand the fracture mechanism of broken soft rock strata more deeply, this paper carried out a series of discrete element particle flow numerical simulations with different...

... and low cost. However, rock fragmentation under the action of blasting is a very fast process, which has brought out great challenges to the research on the failure mechanism of rock blasting. When analyzing the response of underground rock under blasting or other dynamic loads, rock damage is affected...

... and reactivates the landslide mechanism. The results suggest that the topography and unconsolidated rock-soil mass are predisposing factors for reactivation. The hourly precipitation within three hours reached 61.80 mm and induced the Meilong debris flow. The debris flow rushed into the Xiaojinchuan River...

... Abstract Clay-rich rocks are widely used in high temperature and stress environment in a very long term like disposal of high-level radioactive waste, exploring its creep deformation mechanism is essential. Clay minerals, as the essential components of clayey rocks, have a crucial influence...
