摘要
根据公路边坡实际情况,选用恰当的评价方法对边坡安全做出准确判断,是公路防灾减灾工作的重要环节。针对山区丘陵公路边坡稳定性评价中存在着大量模糊性、易变性和随机性因素,传统方法难以满足具体评价需求等问题,优化改进了标准集对分析理论（SPA）,并结合层次分析法（AHP）,构建了基于AHP-集对分析的山区丘陵公路边坡稳定性评价模型。以河南省修武县5处山区丘陵公路边坡为例,该模型先建立由4大因素共14个指标组成的稳定性评价指标体系,再运用层次分析法确定各指标权重,然后通过单指标联系度和综合联系度等计算,求出最终的评价结果。结果表明,研究区1、4、5号边坡稳定性较差,建议采取相应的防治措施;2、3号边坡大体稳定,可留意观察,暂不处理。
According to the actual situation of highway slope, it is an important part of highway disaster prevention and mitigation to make accurate evaluations of slope safety and stability by using appropriate evaluation method. In view of the existence of a large number of fuzzy, volatility and stochastic factors in mountainous and hilly area of the highway slope stability evaluation, and the traditional method is difficult to meet the needs of specific evaluation, this paper optimizes the standard theory of set pair analysis （SPA）, and combining with the analytic hierarchy process （AHP） and based on the AHP- SPA, the slope stability evaluation model of mountainous and hilly highway is constructed. Take 5 places of mountainous highway slope in Xiuwu county of I-Ienan Province as an example, the stability evaluation index system is firstly established by the mode which comprises of 4 factors with a total of 14 indicators, secondly AHP is used to determine the weight of each index, and finally, through the calculation of single index and comprehensive contact connection degree, the evaluation results are worked out. The results show that the No. 1, No. 4 and No. 5 slope stability in the study area are poor, needing to take timely protection and reinforcement measures, and No. 2 and No. 3 slope are generally in safety, only needing observation and no need to take further processing.
