Study on the Evolution Law and the Orientation Criterion of a Plastic Zone in Rock Surrounding a Circular Roadway in a Three-Dimensional Non-Isobaric Stress Field

Study on the Evolution Law and the Orientation Criterion of a Plastic Zone in Rock Surrounding a Circular Roadway in a Three-Dimensional Non-Isobaric Stress Field

The original rock stress field is mainly divided into the σ<sub>HZ</sub>-dominant stress field, the σ<sub>Z</sub>-dominant stress field, and the σ<sub>H</sub>-dominant stress field. Via theoretical analysis, the plastic zone morphology and the orientation of roadw...
