Research about the Rationality of Neighborhood Tunnel Spacing

Abstract:

Analysis of the surrounding rock stress distribution of neighborhood tunnel by using numerical simulation. Based on Cullen-Moore Theory, build a mathematical model of 1st principal stress σ1, 2nd principal stress σ2, internal friction angle φ, and cohesion c, then, make a expression of tunnel spacing safety factor A. Analysis a real tunnel project and evaluate its surrounding rock stability with safety factor A as the index. Propose an analysis method of judging the rationality of tunnel spacing.
