摘　　要：为解决地下工程围岩稳定性评价问题,综合运用AHP和可拓学理论,建立多层次多指标的地下工程围岩稳定性综合评价模型,得出安全等级标准及指标量值.运用AHP确定指标的权重系数,并依据可拓学理论构造经典物元、节域物元和关联函数,建立地下工程围岩的AHP-可拓学预测模型,依据特征值逐一确定30个待识别物元稳定性级别.计算结果表明,理论上适宜依据工程围岩稳定性的各层次指标的权重值和级别特征值,作为评价安全等级标准,对来自同一工程的样本稳定性识别较好,与突变级数法及逼近理想解排序法结果相吻合,该方法可用于地下工程围岩稳定性识别.In order to solve the stability problem of surrounding rock, this paper applied the theory of AHP and extenics to establish a multi-layer comprehensive evaluation of underground engineering stability, and obtained the safety level standard and the evaluation index. The weight vector about safety index was determined by AHP, and the elements in classical and joint field, correlation function of matter elements in extension sets were structured by extenics theory. The AHP-extenics model of underground engineering surrounding rock was established, and every safety level of 30 samples was obtained based on the characteristic value. Through the calculation of the model, the research results are obtained by the weight values on the index layer and the characteristic value on the rule layer, which are better and consistent with those of the catastrophe progression method and TOPSIS method based on the same engineer.
