万家寨引黄工程联接段施工控制网的技术设计

Technological Design on Construction Horizontal Control Survey Network Of the Connection Works,the YRDP

本文既考虑了万家寨引黄工程联接段的管道安装精度 ,又考虑了隧洞贯通精度。在考虑两项精度的基础上设计出联接段施工平面控制网的精度 ,并设计了施工平面控制网的坐标系以及采用GPS布点的技术设计。

Based upon considering both the pipeline installation precision and the turnneling's holing through precision in the Connection Works,the YRDP,the precision of the construction horizontal control survey network of the Connection Works is given,then the coordinate system of the construction horizontal control survey network,the principle,observation requirement and data process of the GPS stationing,and the precision of the tunnel elevation are determined.
