| 摘 要： | 基于可拓学理论,建立了山区公路安全评价物元模型.将该模型应用于山区公路的安全评价研究,以克服模糊数学和专家评分等方法对模糊和非定量化指标评价精度不足的问题.通过关联函数,可以精确的确定待评价的路段关于各个评价等级的关联度,从而能够全面准确的评价路段的安全等级.此外,还建立了山区公路安全评价指标体系,通过实际算例说明了该模型及评价指标体系能够有效解决非定量化评价问题.

| Abstract: | A matter-element model about safety evaluation of highway in mountainous regions is established on the basis of the theory of extenics.The model is applied to safety evaluation of highways in mountainous regions for overcoming the deficiency in evaluation accuracy that exists in fuzzy mathematics and experts grading method,especially for non-quantitative and fuzzy indexes.Using the correlation function,the correlation degree can be accurately determined for the highway sections to be evaluated.Thus,the safe... |
