摘　　要：为预防与防治地裂缝重新开启或加剧破裂扩展,降低工程建设经济损失。以西安地裂缝作为分析平台,将AHP与模糊数学综合评判法引入到地裂缝灾害系统评价中,结合两者模型的优点,应用AHP法确定评价因素权重;运用模糊数学方法,根据评价因素构造隶属函数,进行模糊综合评判,依据最大隶属度原则,对地裂缝灾害进行等级评价。研究结果表明,地裂缝灾害等级为“严重”,其评价结果与西安地裂缝实际情况对比是一致的。In order to prevent the reopening and anabatic expansion of ground fissure, and reduce the economic loss of the engineering construction, this paper fully integrate AHP method and fuzzy mathematics comprehensive evaluation method to study Xi’an ground fissure. AHP method is used to determine the weight of evaluation factors, and the fuzzy mathematics method is used to construct membership function according to evaluation factors. The grade evaluation of ground fissure disaster is carried out according to the principle of maximum membership degree. The results show that the grade of ground fissures is seriousness, and the evaluation results are consistent with the actual situation of Xi’an ground fissures.
