Abstract: A new grouting simulation device was developed to study the influence of property of grout slurry on grouting pressure and slurry diffusion. This device substituted overall filling and compaction of soil of layer-compacting to avoid the occurring of interlinear interface. Thus the influence of interlinear interface on slurry diffusion could be decreased. Grouting pressure and slurry diffusion of sodium carboxymethyl cellulose solution, simulating Newtonian slurry, cement slurry and cement-silicate slurry were studied by simulation experiment, and then validated by theoretical analysis. The results showed that property of grout slurry had remarkable influences on change laws of grouting pressure and splitting feature. Slurry diffusion pattern could be abstained by analyzing the change laws of grouting pressure in combination with splitting feature.

Key words: grouting pressure, reinforcement mechanism, grouting diffusion, grouting material property
