Abstract EN
In order to study the diffusion law of grouting slurry in sand areas, the grouting of cement slurry in sand was analyzed by the indoor grouting test under different water-cement ratios, grouting pressures, grouting amounts, and soil qualities, and the law of the post-grouting slurry is obtained.
The results show that the grouting method is affected by the grouting pressure, water-cement ratio, grouting amount, and soil quality.
Under the same grouting pressure, the diffusion modes of different water-cement ratio grouts in sands with different permeability coefficients, which are mainly manifested as osmotic diffusion, are basically the same; under the same water-cement ratio, when the grouting pressure is relatively small, the diffusion of modes of slurry is mainly osmotic in sand.
The diffusion radius of cement slurry in sand has a good power function relationship with grouting pressure, water-cement ratio, permeability coefficient, and grouting amount.
And, the empirical function model of slurry diffusion radius is proposed by regression analysis.
The research results provide a certain theoretical and experimental reference for post-grouting in sandy areas.
