Design and Analysis of Grouting Pressure in Slurry Pipe Jacking Based on the Surrounding Soil Stability Mechanical Characteristics

Figure 2

Schematic diagram of the whole process of grouting disturbance. (a) Initial grouting and filling overcut area. (b) Slurry seepage and forming slurry-soil mixture. (c) The slurry compresses the soil and forms a filter cake. (d) The surrounding soil maintains it stability at excavation hole. (e) The surrounding soil lose it stability at excavation hole.
