Influence Research for Softening and Swelling of Weakly Cemented Soft Rock on the Stability of Surrounding Rock in Roadway

Figure 10

Distribution of plastic zone of weakly cemented soft rock roadway surrounding rock under different simulation schemes (red: shear failure, blue: shear-tension failure). (a) Scheme 1: without softening and expansion. (b) Scheme 2: with expansion. (c) Scheme 3: with softening. (d) Scheme 4: with softening and expansion.
