摘要
综合管廊是城市地下公共设施空间可持续发展的最好方式之一。综合管廊建设应"规划先行",而节点作为引导综合管廊网络布局形成的重要组成部分,对综合管廊的规划起着重要作用。本文引入复杂网络理论,将道路网抽象成为加权复杂网络,首先建立管廊路径适建性评价模型确定路径适建性权值;其次,将路径适建性权值赋于路网的边,结合综合管廊自身特点对节点收缩法进行改进,评价综合管廊网络节点重要度;最后通过工程案例进行验证,并利用K-means进行聚类分析,确定节点重要度优先级。研究结果表明,综合管廊规划布局时,可根据节点重要度优先级选择综合管廊布局的控制点,为综合管廊最优路径规划提供依据。
        Utility tunnel is one of the best ways for sustainable development of urban underground public space.The construction of the utility tunnel should be"planning first",and the nodes play an important role in the utility tunnel planning to guide network layout. In order to plan more scientifically and reasonably,it is necessary to find the important control points needed for the planning. Complex network theory is introduced into this paper to abstract the road network into weighted complex network. Firstly,the path suitability weight of the utility tunnel is obtained by establishing evaluation model of the utility tunnel. Secondly,the path construction weights are assigned in the edge of the road network,and the concept of point right is redefined. And the different effects of the primary and secondary roads on the importance of the nodes are added combining with the characteristics of the utility tunnel,and then the improved weighted network node contraction method is used to evaluate the importance of utility tunnel network node nodes. Finally,the project case verifies the efficiency of the proposed method,and using K-means to cluster analysis to prioritize nodes. The results show that the weighted importance of the weighted network node constraining method is more in line with the actual planning and construction requirements of the utility tunnel. Control points can be selected based on node priorities to form optimal path planning in utility tunnel planning.
