Abstract: It’s the important task to make sure the stabihty of the perilous rock，which determines whether the countermeasures to perilous rock are carried out．At the same time，the identification of the stability of the perilous rock is the prerequi- site for the quantitative calculation．The comprehensive index method based on AHP is adopted，to carry out the comprehen- sive stability evaluation of the old and perilous rocks and corresponding monomer in Yubei district，which is aiming to pro- vide reliable evidences for the countermeasures of perilous rocks in this area．

Key words: AHP, comprehensive index method, perilous rock, stability evaluation

摘要： 危岩的稳定性确定是危岩勘查的重要任务，决定着是否需要对危岩进行治理，在危岩的稳定性判别中定性判 断是定量计算的前提。采用基于层次分析的综合指数法，对渝北区老岩危岩相关危岩单体逐一进行稳定性综合评 价，旨在为该区域危岩的防治提供可靠依据
