摘要
为准确有效地对复工高速公路路基质量进行评价,在传统物元可拓分析模型的基础上,建立了复工高速公路路基质量评价的熵权物元可拓模型,通过熵权理论确定权重,避免确定指标权重的主观随意性,并用该方法对洪萍高速公路中K18+700、K18+885两个里程段路基进行质量评价。研究结果表明:路基质量评价结果与现场实际情况一致,且该方法科学合理,为类似研究提供了一条新的技术途径。
In order to evaluate the subgrade quality of rebuilding highway accurately and reasonably,an entropy-weight and matter-element extension model was established on the basis of traditional matter-element extension model. The weights were determined by entropy-weight theory,which avoided non-determinacy and optional randomness resulted from subjective opinions. This model was applied to evaluate the Hong Ping highway subgrade in K18 + 700 and K18 + 885 paragraph miles. The results showed that the evaluation result was consistent with the actual situation,which proved that the entropy-weight and matter-element extension is scientific and reasonable; furthermore,it can provide an effective method for the similar research.
