摘要
介绍了大连市沿海丘陵地区地铁施工控制网布设、观测中关键技术的研究及解决方案,其中利用GPS静态观测与传统精密导线测量相结合组成混合网平差、将精密导线点纳入二等水准网,实现平高复用等技术,可给同类工程实施提供参考。
Dalian coastal hilly region are introduced in subway construction control network, and the study of the key technologies of the observation and solution, including using GPS static observation combined with traditional precision traverse survey of mixed net adjustment, the precision traverse points into the second grade level net fiat high reuse technology to provide reference for similar pro- ject.
