摘要 软基处理方案决策影响因素有不完全性、未知性等特点 ,软基处理方案决策实质上是灰色系统问题。运用灰色系统理论 ,建立了一种新的软基处理方案决策模型。合理确定了方案决策评价指标及其权重 ,根据计算出的灰色关联度来实现对拟选方案的优选和排序 ,从而对方案作出决策 ,实例分析表明 ,该模型使用方便、决策结果合理 。 The factors that affect the decision of soft ground improvement methods have the features of incompleteness and uncertainty and thus making a decision of the soft soil improvement methods a grey system theory problem. Using the grey system theory, the new decision model is established. In this model, the evaluation indexes of the schemes and their weights are reasonably decided and the optimal scheme is selected by calculating the relational grade to realize the selection and order arrangement for the schemes. The actual examples' results indicated that the decision model is reasonable, practical and convenient to use.
