【摘要】：针对山区丘陵公路边坡安全存在多种随机性、模糊性和不确定性因素等问题,优化改进了标准集对分析理论,并将熵权-集对分析模型应用于公路边坡安全评价中。以河南省修武县5处典型山区丘陵公路边坡为例,构建了由4大类共14个指标组成的评价指标体系,再利用熵权法确定各指标权重,最后通过单指标联系度、综合联系度等计算,得出综合评价结果。结果表明,1、4、5号路段边坡安全性较差,建议采取及时的防治措施;2、3号路段边坡大体安全,可留意观察,暂不处理。与传统方法相比,熵权-集对分析模型理念清晰、计算简单、准确度高、实用性强。
[Abstract]:Aiming at the problems of randomness, fuzziness and uncertainty in the safety of mountain hill highway slope, the standard set pair analysis theory is optimized and improved, and the entropy weight set pair analysis model is applied to the evaluation of highway slope safety.Taking 5 typical mountain hill highway slopes in Xiuwu County, Henan Province as an example, an evaluation index system consisting of 14 indexes of 4 categories is constructed. The weight of each index is determined by entropy weight method, and finally, the relation degree of single index is adopted.The comprehensive evaluation results are obtained by the calculation of the comprehensive connection degree and so on.The results show that the safety of the slope is poor in the sections of No. 4 and No. 5. It is suggested that timely preventive measures should be taken for the safety of the slopes of the sections No. 2 and No. 3, which can be observed and not dealt with for the time being.Compared with the traditional method, the entropy weight set pair analysis model has the advantages of clear idea, simple calculation, high accuracy and high practicability.
