道路基础设施管养标准图谱体系

Standards Graph System of Road Infrastructure Maintenance and Management

为提升道路基础设施管养标准体系的一致性和完整性,探究了对道路基础设施管养影响较大的重要标准并分析了标准体系的时间、地域特色。建立道路基础设施管养标准规范的引用网络,使用度中心性、半局部中心性、PageRank算法估复杂网络中关键节点的重要性,并引入逼近理想解排序(TOPSIS)法进行综合评估,从标准引用网络中挖掘出具有重要性、代表性、权威性的标准规范。此外,使用基于词云的词频统计方法分析了不同时间段内标准和3个不同地理分区地方标准的主题热点,得到养护技术、养护对象的特点。通过道路管养标准图谱梳理了道路基础设施管养标准的关联与脉络,为完善标准体系提供了重要参考。

To improve the consistency and integrality of the road infrastructure maintenance and management standard system,crucial standards which have an essential effect on infrastructure industry are explored and temporal and reginal characteristics of the standard system are analyzed in this paper.After establishing a standard graph of road infrastructure maintenance and management,an importance analysis on key nodes in the complex network is made to find the important,representative and authoritative standards by using the degree centrality,semi-local centrality and PageRank algorithm.And the technique for order preference by similarity to an ideal solution(TOPSIS)is introduced for comprehensive evaluation.In addition,a word cloudbased frequency statistics method is used to analyze the hotspots of standard topics in different time periods and three different geographical zones,acquiring characteristics on maintenance objects and technologies.By establishing a road maintenance management standard graph,the correlation and context of road infrastructure maintenance and management standards are sorted out,providing an important reference for the improvement of the standard system.
