摘　　要：软土的沉降等级评价是一个复杂不确定系统问题,在集对分析中利用线性内插法对差异度系数i进行取值从而充分利用约束条件,进而建立软土沉降分类模型,并利用熵权法充分挖掘待评价数据的内部因素,进而提高了评价结果的可靠性和准确性,并用于实际的软土沉降评价,且与其他方法进行了比较,结果表明,该方法充分挖掘了待评价数据,所得结果有效且更加客观.The settlement evaluation of soft soil is a complex and uncertain system problem. In the set pair analysis, the linear interpolation method is used to get the value of the difference coefficient i to make full use of the constraint conditions. Then the soft soil settlement classification model is established and the entropy is utilized. The power law fully exploits the internal factors of the data to be evaluated, and then improves the reliability and accuracy of the evaluation results. It is used for the evaluation of actual soft soil settlement and compared with other methods. The results show that the method fully exploits the data to be evaluated. The results obtained are valid and more objective.
