【摘要】 提出以道路及相关设备为节点、约束关系为边的路网约束关系超图语义模型,全面准确地描述路网复杂耦合约束关系;建立交叉口判别准则,研发交叉口自动判别算法以及路网超图更新算法,实现了路网超图模型的动态维护;以诺尔盖车站工区路网设计为例对模型进行验证,结果表明该模型很好地满足设计需求。此外,该模型可拓展应用于城市路网、地下管线设计等领域。更多还原

【Abstract】 This paper presents a semantic hyper graph model which takes roads and relevant facilities as nodes and the constraint relationships as edges to describe these complex cross-coupling relationships; The criterion for automatic distinguishing intersections was established.After that,the network hypergraph model can be maintained dynamically by updating algorithms.At last,this paper took road network design in the Ruoergai station as a case to verify the model.The result shows that the model meets the design requirements well.Besides,this model can also be applied extendedly to the design of urban road network and the underground pipelineetc.更多还原
