Grouting reinforcement was used to improve rock strength and avoid seepage in rock
engineering. A self-developed visualised test platform was developed and the influences of …

In this study, a testing device was developed to analyze the characteristics of grouting
diffusion in faults. To include the interaction of multiple grouting applications, tests consisting …

Grouting is a widely used geotechnical procedure known for its strong empirical properties. It
has been extensively utilized for sealing subterranean water and strengthening soil and rock …

The flow process of grout in a rock mass fracture network is an important part to judge the
effect of grouting in engineering. Till date, little research has been done on the diffusion and …

Grouting reinforcement is an important method used to solve problems encountered during
tunnel construction, such as collapse and water gushing. The grouting diffusion process is …

In this study, we present a single splitting grout diffusion model based on the Bingham slurry,
considering the time variability of viscosity and rock type I fracture toughness. The …

Grouting method is an effective way of reinforcing cracked rock masses and plugging water
gushing. Current grouting diffusion models are generally developed for horizontal cracks …

Because of the limitation of mining techniques and economic conditions, large amounts of
residual coal resources have been left in underground coal mines around the world …

Due to the influence of fracture undulation, there is an obvious difference in the grout flow
rule between the rock mass with rough fractures and the rock mass with existing results …

The surface roughness of grout in fractured rock masses has a significant impact on the
diffusion characteristics of grout, especially in millimeter-scale fractures. In this study, a self …
