摘要
The stability evaluation of the surrounding rock of tunnel with small clear spacing is an important step in a tunnel construction process. In this paper an indicator system was proposed to evaluate the stability state of the central rock pillar between twin tunnel with small clear spacings; then an AHP (Analytic Hierarchy Process) model was constructed to calculate the weights of indicators; and finally, with fuzzy mathematic method, a fuzzy comprehensive evaluation model was set up to evaluate the stability state of the central rock pillar between twin tunnel with small clear spacings. Project cases showed that this method is practical and effective. (C) 2011 Published by Elsevier Ltd.
