摘要
供水管线系统是否完善是衡量城市规划是否合理的重要指标,其中设施的定位至关重要,将直接影响到整个管线系统的质量及维护更新和事故排查的效率。针对供水管线分布密度高、更新速度快、类型复杂等特点,CORS是一种实用有效的测量定位方法。本文研究CORS在城市供水管线测量定位中的应用,结合武汉市管线设施竣工测量的案例,用多项指标验证了成果的精度及该方法的可行性,并结合其他定位方法分析,为供水管线设施的定位提供参考意见。
Whether the water pipeline system is perfect or not is an important indicator of whether a urban planning is reasonable or not, and the plumbing facilities positioning which will directly affects the quality and the efficiency of ma- intenance, updating and troubleshoot of the entire pipeline system is critical. For characteristics of high distribution den- sity, high updating speed and complexity of types of the water pipeline facilities distribution, CORS is a practical and ef- fective measuring and positioning method. The article studies the application of the CORS in measuring and positioning of urban water pipeline, and combined with the cases of the completion measuring of water pipeline facilities in Wuhan, verities the accuracy and feasibility of measuring result of this method with various kinds of indicators, and by comprehensive analysis combined with other positioning methods, provides reference for the positioning methods of the water pipeline fa- cilities.
