太原西山特长隧道高精度施工控制网的建立

Establishment of Control Network with High Precision for Xishan Tunnel in Taiyuan

介绍太原西山特长隧道高精度施工控制网的设计方案、施测过程和测量精度结果。同时,该项目首次在国内同类工程中使用GPS似大地水准面精化成果和全球卫星定位连续运行参考站(CORS)服务系统技术,效果良好,其积累的经验为今后的类似工程建设提供了借鉴。

In this paper, the design schemes of controlling network, measure process and results of precision during construction for Taiyuan Xishan long tunnel are introduced. At the same time, it is the first time that GPS geoid refinement results and Continuous Operation of GPS Reference Stations （CORS） system technology are used in this project with good effect. The experience will provide a reference for similar projects in future.
