| 摘 要： | 深基坑支护工程是一个复杂的系统工程 ,不仅具有多目标性且具有模糊不相容性 ,在分析目前深基坑支护方案决策中存在不足的基础上 ,综合运用层次分析法和信息熵理论确定评价指标的权重 ,把各种支护方案作为物元的事物 ,以它们的各项评价指标及其相应的模糊量值构造复合模糊物元 ,建立了支护系统方案评价的模糊物元模型 ,通过一个工程实例证明了该模型的合理性和有效性 .

| Abstract: | Supporting projects of deep foundation pit, with its characteristics of multi-objective and fuzzy incompatibility, is a complex system project. By analyzing the disadvantages of the latest decision making methods, combining analytic hierarchy process with information entropy theory to determine the evaluation indexes' weights, supporting projects are considered as different matter-elements. Compound fuzzy matter-element is founded by integrating evaluation indexes and fuzzy values of matter-elements. And fuzzy matter-element model for evaluating supporting system is established. The model is proved to be reasonable and effective by an engineering example. |
