discussed. The results show that elastic modulus and thickness are advantageous to the floor stability, and that the load, span, horizontal stress and water are disadvantageous to the floor stability..., critical safety thickness is supposed to derive with necessary and sufficient condition, and the effect of horizontal stress has important influence in deep-buried tunnel. Rock system should......
