摘要
目前国内外对于坑槽的修补技术较多,但是在具体的情况下如何进行养护决策尚未有好的解决方法。因此,如何在考虑费用、寿命、效率等因素的情况下对这些修补技术进行客观科学的综合评价就尤显重要。现有的养护技术评价方法存在着主观性较强、指标单一和指标取值不合理等问题,导致评价结果偏差较大。笔者综合了经济、社会、技术等方面的指标,在层次分析法的基础上,结合模糊数学和统计学法,建立了针对坑槽修补技术的改进层次模糊评价体系。运用该体系对坑槽修补技术进行优选,并与其他方法计算结果进行对比,结果表明该方法合理可行。
Nowadays there are many kinds of maintenance technologies at home and abroad, but which treatment is preferable in different conditions is hard to decide. Therefore, it is particularly important to evaluate these repair technologies scientifically and objectively in terms of expense, lifetime, benefit and so on. The existing maintenance technology evaluation methods are subjective, single, and unreasonable to some extent, and the results are prone to be biased. Combining with economic, social, technological and other factors, this paper proposes an improved hierarchical-fuzzy evaluation system for potholes maintenance technolo- gy, based on analytic hierarchy process, integrating fuzzy mathematics and statistics. Results show that, compared with other methods, the hierarchical-fuzzy evaluation method is reasonable in selecting the optimized pothole treatment.
