摘要(Abstract)：
针对城市地下管线结构复杂且信息量大,显示、管理与分析具有一定难度的问题,该文提出利用附属工井墙壁的管孔节点进行井内电缆及井间管道的连接,实现地下工井电缆网络的构建。该方法在建模方面,主要针对多种电缆进行数字化表达,突破管线电缆传统单一化的点线化建模方式,采用改进标架的Sweep算法对井内电缆进行抽象模拟或对其形状及走向进行实际模拟,使电缆具有多样性且在拐点处不出现扁平化;在拓扑关系构建方面,利用管孔节点来进行电缆与管道的连接。拓扑连接将部件化的电缆和管道元素整体化,实现了满足局部查询监测的庞大空间网络系统。在实际应用中,本方法为施工者及管理者监测井内实际情况、管理及查询城市地下管网提供支持。
