摘　　要：隧道工程是受各种复杂因素影响的地下结构工程,虽然通过监测工作得到的隧道净空位移变形可以一定意义上有效反映隧道是否稳定,但是却无法对隧道的整体稳定性情况做出合理的判断.为了更好地解决这一问题,利用模糊数学的原理对各影响因素进行有效度量,并利用层次分析法的原理确定各影响因素之间的权重.这个评估模型综合考虑了影响隧道稳定性的几个主要因素,能很好地反映隧道围岩的稳定性情况,使评估结果更具有科学性和合理性.Tunnel engineering is the underground structural works which are subject to a variety of complex factors.Although the deformation of the tunnel clearance displacement can,to a certain extent,effectively reflect the stability of the tunnel,it cannot make reasonable judgments about the overall stability of the tunnel.In order to better address this issue,this paper applies the principle of fuzzy mathematics to weigh various affecting factors effectively,and uses the principle of AHP to determine the relation among these factors.This evaluation model takes into account comprehensively the impact of several major factors on the stability of the tunnel,and can well reflect the stability of the tunnel surrounding rock,thereby making assessment more scientific and rational.
