广州地铁六号线二期工程平面控制网测量

Measurement of Horizontal Control Network of Guangzhou Metro Line 6

控制网是地铁工程建设的重要基础,以广州地铁六号线二期控制网为例,较详细介绍地铁施工控制网的设计、布点原则、施测等重要过程,对测量成果精度进行比较分析,得出控制网与原一期控制网平顺连贯,满足地铁六号线二期工程设计施工对控制网的精度要求。

The control network is an important basis for subway construction, take the Guangzhou Metro Line Phase Ⅵ control network for example, more detailed network design of metro construction, distribution principle, sampling and other important processes were introduced, to compare and analysis the accuracy of the measurement results to get the smooth coherent control network with the original one ,to meet the sixth line of the MTR design and construction of Phase Ⅱ accuracy requirements on the control network.
