摘要：
A theoretical model of the moving interface of grout was established on the basis of continuity equation of penetration, Darcy's law and linear filtration law. The migration and plugging mechanism on the slurry interface was analyzed. The variation of designed spreading distance of grout and the permeability of the deposition layer were investigated using the model test system developed in-house. The experimental data were compared with the theoretical values. The results show that the designed spreading distance is dependent on the designed upper limit of coefficient of permeability and the grouting parameters. Influenced by the deep bed filtration effect, the coefficient of permeability of the deposition layer varies along the slurry interface migration. © 2016, Science Press. All right reserved.
