摘　　要：为保障大兴安岭多年冻土区道路工程安全运营,从众多影响因素中选择冻土环境、自然环境和工程措施等建立评价集,确定评价指标的等级标准。运用模糊数学的隶属度理论,建立多年冻土区路基模糊综合评价模型。依据大兴安岭地区中俄原油管道漠大线林区伴行路典型路段监测数据,对模型评价结果进行验证分析。结果表明,模型评价结果与实际道路路基病害一致性较高,该评价方法可应用于冻土路基热稳定性评价,具有一定的实用性。In order to ensure the safe operation of road engineering in the Daxing'an Mountains permafrost area,this paper selected the permafrost environment,natural environment and engineering measures from a large number of influencing factors to establish an evaluation set and determine the grade standard of evaluation indexes.Based on the membership degree theory of fuzzy mathematics,a fuzzy comprehensive evaluation model of subgrade in permafrost area was established.Based on the monitoring data of the typical subgrade of the accompanying road in the permafrost area of the Mohe-Daqing line of China Russia crude oil pipeline in Daxing'an Mountains area,the results of the evaluation model were verified and analyzed.The results showed that the model evaluation results were highly consistent with the actual road subgrade diseases.The evaluation method can be applied to the thermal stability evaluation of frozen soil subgrade,and has certain practicality.
