 The Auditon Finite Difference Method software was used to simulate the dynamic stress distribution and fracture area of rock around a tunnel under different orientations of blasting disturbances. Real-time monitoring of the stress distribution, displacement and fracture area of the tunnel was conducted using gauge monitoring points. The results showed that the stress and displacement of the tunnel was smaller when the blasting disturbance source was located above the roof, and the stress state of the tunnel was relatively stable with minimal fracturing. Horizontal direction stress had the greatest effect on the displacement of the tunnel, which was mostly concentrated above the floor and at the shoulders. Vertical wall parts had little displacement due to the lack of horizontal direction stress. Brittle materials like rock have an arch-shaped stress-bearing surface, making them more susceptible to failure. This arch shape allows for better disbursement of stress, leading to less uneven stress on the stress-bearing surface and less uncoordinated deformation.
