| 摘 要： | 针对立体交叉方案综合评价的多目标、多层次等特点，运用多层次灰色理论的方法，对可比性方案通过综合评价选出最优方案。通过对立交方案因素指标分层及参考数据的确定，采用层次分析和灰色理论相结合的方法，对各层指标相对权重进行了确定和检验。借助灰色关联分析，计算了立交方案的综合关联度。根据关联度越大排序越前的原则，确定出最优方案。工程实例表明，多层次灰色理论应用于立交方案综合评价简单易行，且考虑了各因素的相关影响，结论更符舍实际。

| Abstract: | When comprehensively evaluating interchange plans, the evaluation system has those charateristics of multi-targets and multi-layers. According to those features, the multi-levels grey system is applied to the evaluation system to select the most superior sheme from the comparable plans. The level analysis method is combined with grey system theory to decide the relative right weight of every indices in the evaluating system. The synthetical grey related degree of every plans is calculated with grey related analysis method. The biggest one is the best plan. A project example shows that this method is easy and feasible and has a good accordance with the reality. 4 tabs, 6 refs. |
