The evaluation system of small-distance tunnels central pillar stability indicator was proposed,and AHP model of the index system weights was made with arrangement analysis method,and then the index weights was fixed.Finally the fuzzy comprehensive evaluation model of the central pillar stability in neighborhood tunnels was established by fuzzy mathematics method.Practicability and validity of the model have been proved through the engineering cases.
