Research on the grouting plugging mechanism of layered jointed rock mass based on the time-varying yield stress of grout

Yalei Zhe,

et al.

Abstract: The key to successfully treating water disasters with grouting is the diffusion range and the grout's ultimate efficient retention in the cracks; the gel qualities of the grout are crucial in this process of diffusion plugging. In earlier research, the time-varying viscosity of grout was given more attention than the yield stress, which is also subject to variation that grout must pass through to migrate. Groundwater migrates and stores through the interlayer opening fissure and vertical connecting fissure in … Show more
