摘　　要：基于前人的研究成果和对冻土地区路基资料的调查分析,从热量因素、水分因素、工程地质因素以及设计因素4个方面评价了冻土区路基稳定性。利用层次分析法结合模糊数学理论,选取了13项起主要影响的指标作为评价指标,通过确定各个影响因素对目标的权值,将因素的影响程度进行数学化,提出了一种科学合理的评价方法,建立了冻土区路基稳定性评价体系,对冻土区路基稳定性进行评价。Based on the previous research results and the investigation and analysis of subgrade data in permafrost regions,this paper evaluates the subgrade stability in permafrost regions from four aspects:heat factor,water factor,engineering geological factor and design factor.By using AHP and fuzzy mathematics theory,13 main influencing indexes are selected as evaluation indexes.Through determining the weight of each influencing factor on the target,the influence degree of the factors is mathematicized,a scientific and reasonable evaluation method is proposed,and the evaluation system of subgrade stability in frozen soil area is established to evaluate the subgrade stability in frozen soil area.
