Grouting Mechanism of Cement-Based Slurry in a Concentric Annulus under High Groundwater Pressure

<div>Comparisons of prediction and numerical simulation results under constant grouting pressure conditions. (a) Overpressure distribution in the grouted zone for the CG at three grouting times, 15, 35, and 55 s. (b) Variations in penetration and grouting flow rate with injection time.</div>
