摘要

结合（湘）潭-邵（阳）高速公路膨胀土的判别实践，运用属性数学理论，建立基于客观性权重的膨胀土属性识别模型。验证和运用结果表明，属性识别模型的判别结果与《公路路基设计规范》评判法、模糊综合评判法的评价结果有较好的一致性。由于属性识别理论能很好地解决某类具有多个模糊属性的综合评价问题，其识别准则是根据某些评价类具有有序性这一特点而提出的置信度准则，且评价模型采用客观性权重，避免了权重确定中的主观性和随意性，保证了评价工作的客观性和准确性，因而评价结果更可靠。

Abstract

Aiming at expansive soil judgment in Xiangtan-Shaoyang Expressway

the attribute recognition model based on objective weight is developed in this paper. The verification and application of this model indicate that the methodology is coherent to that of the Specifications for Design of Highway Subgrades and the fuzzy synthetic evaluation method. Because the attribute recognition theory would well determine some kind of synthetic evaluation problem with fuzzy attributes and its confidence criterion is developed in terms of some evaluation sets with ordered characteristics

furthermore

this model uses objective weight as the weight of the evaluation indices

decreases the subjectivity of weight decision

and ensures the objectivity of evaluation

thus the evaluation results are much more reliable.
