| 摘 要： | 基于可拓工程方法，在物元模型理论的基础上建立了公路泥石流危险性评价的物元模型，并采用层次分析法计算物元模型中各评价指标的权系数。通过实际公路泥石流危险性等级的关联度计算，对四川地区雅泸高速公路的5条泥石流沟进行了评价，得出与实际相符合的结论。并与其他评价方法相比表明：该方法不仅可以应用在泥石流危险性评价上，而且所得的结果会更加合理，具有较好的适用性。

| Abstract: | The matter element model of debris flow hazard assessment about highway in mountain area is established using matter element model theory based on extension engineering method.The stratification analysis method used to calculate weight aggregation of evaluating factors is proposed.of Debris flow hazard of five valleys is evaluated through calculating the relational degree of the actual debris flow hazard grades,which are situated along Ya'an Luding highway in Sichuang.Compared with other assessment methods,... |
