Abstract: Chloride diffusion is one of the major causes of deterioration of concrete structures. A large amount of research has been conducted to study the chloride diffusion of concrete, both theoretically and experimentally. Because ...

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: Internet-based transportation systems are becoming widespread due to advances in Internet, computing, and geospatial information system (GIS) technologies. An internet-based methodology that allows public transportation ...

Abstract: The effects of calcium nitrite solution, fly ash, silica fume, and their combination on the alkali-silica reaction were studied experimentally according to ASTM C 227 (mortar bar test). To explore the mechanism of such ...

Abstract: An energy parameter based on the concept of the

Abstract: Accurate detection and quantification of damage to railway fasteners are crucial for ensuring railway safety. The spatial damage defects caused by the complex shape of fasteners and the problem of data imbalance in actual ...

Abstract: Controlling tunnel response induced by lateral excavation in soft clay has become a significant focus of modern research. Capsuled expansion is an innovative active control technique used to control the deformation of ...

Abstract: Brittleness has a significant influence on rock failure under compression; however, the mechanism is rarely comprehensively discussed. This study numerically investigates the brittleness effect on microcracking behavior ...
