对水利工程建设中各类测量平面控制网的分析

Analysis of Plane Control Network for All Kinds of Water Conservancy Construction Measurement

水利工程建设不能只用一个测量平面控制网,这会给具体的施工带来很大不便,甚至还可能导致质量问题。在水利工程建设中至少要建立3种测量平面控制网,它们分别是:测图平面控制网、施工平面控制网、变形监测平面控制网。这3种平面控制网在坐标系建立方式、精度上都有不同的要求。

The construction of water conservancy project can not only use one measurement plane control network,this will bring inconvenience for the construction,even result in quality problems.At least three kinds of measurement plane control network should be established during the construction of water conservancy project,and they are mapping plane control network,construction plane control network monitoring network respectively.The three plane control networks have different accuracy requirements in the coordinate system.
