摘　　要：膨胀土及改良土胀缩性评价是确定膨胀土地基处理工程的首要任务。本文探讨了基于可变模糊集理论的膨胀土和改良土胀缩性综合评价模型,结合合肥新桥机场膨胀土地基处理工程中膨胀土和改良土的综合评价应用,并与一般模糊数学方法结果进行了对比分析,取得较好效果,也为工程建设提供了重要依据。The reasonable evaluation and classification for swell and shrinkage of expansive soils and improved soils are primary tasks for the foundation treatment.Based on a variable fuzzy set theory,a comprehensive evaluation model was discussed.Moreover,this proposed model was used to analyze swelling and shrinkage classification of expansive soils and improved soils for the foundation treatment in Xinqiao airport of Hefei,and comparison with results form the fuzzy mathematics method was further conducted.It indicated that the result was good,and provided important reference data for construction of airport runway on the expensive soils.
