This study aims to explore the mechanical behavior of rock masses with structural planes using a mesoscopic perspective. The particle flow code two-dimensional numerical simulation software is employed investigate effects confining pressure and plane dip angle on failure characteristics, behavior, slip masses. research finds that, under constant pressure, peak stress elastic modulus initially decrease then increase as rises, minimum values observed at 65° angle. At same angle, both strength increasing pressure. For typical sample 35° increases, concentration extends from plane, displacement decreases top bottom, larger upper measurement point. As rocks transition tensile shear failure, back failure. Lower pressures lead sliding smaller angles. correlation between strength, strain found be high, approaching 1, while number fractures relatively weak. Based expression components normal critical conditions, relationship equation derived. highlights role characteristics in mass provides valuable insights for engineering applications.
