Investigations of the flow and diffusion mechanism of grout slurry in underground fractured
rock mass are of critical significance to guarantee the grouting reinforcement of deep soft …

Due to the invisibility and complexity of underground engineering rock masses, it is
extremely difficult to observe the diffusion process of dynamic water grouting. Therefore …

In this study, the low-field nuclear magnetic resonance (NMR) testing technique was
adopted to experimentally investigate the seepage processes of chemical grout flow in …

Investigation of the seepage characteristics and the corresponding repairing effects of slurry
on fractured rock mass is of great significance to grouting theory and operation parameters …

In order to solve the water and gas discharge hazard caused by gob water and harmful
gases (such as CO), the method of grouting overburden fractures is adopted to achieve the …

Although grouting has been widely used in tunnels to seal groundwater inrush and reinforce
rock masses, dynamic water grouting in fractured rock remains challenging. Carbon fibre …

Grouting methods are known to effectively remediate the groundwater inrush in tunnels with
weak water-rich sand layers. However, the diffusion characteristic of cement slurry flowing in …

It is of great theoretical significance and engineering application value to research the
diffusion law of slurry in mining fractures of rock strata to enrich grouting theory and improve …

Quick setting grout is used in permeation grouting projects to control the grouting diffusion
range effectively and reduce the waste of grout. Owing to the double-component injection …

Silty fine sand stratum with a high water groundwater level is a common soil type with poor
strength. During tunnel construction and foundation pit excavation, geologic hazards such …
