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

Figure 6

The calculation results for the flow rate control injection mode. (a) Viscosity distribution with penetration length at three grouting times, 15, 35, and 55 s. (b) Overpressure distribution with penetration length at three grouting times, 15, 35, and 55 s. (c) Variations in grouting overpressure with injection time.
