万家寨引黄工程连接段施工控制GPS网的优化

Optimization of GPS Network For Construction Control of the Connection Works of the YRDP

本文主要论述了引黄工程连接段施工平面控制网的技术设计，经过论证，在布网方案采用的等级、施测方法等方面均进行了优化，从实测的各项精度列表统计看，都达到了有关《规范》和设计的各项要求，最终成果为施工提供了高精度、真实可靠的坐标依据。

The technical design of the horizontal control GPS network used for construction of the Connection Works of the YRDP is illustrated,in which optimization is done in selection of the scheme of network layout in grade used and in survey method.The survey results meet each item of accuracy requirement of the relevant staneard and of the design,providing a high-accuracy and high-reliability coordinate basis for the construction.
