摘要
介绍了中天山隧道平面控制网建网的网型设计、观测和数据处理,分析了该隧道控制网的观测质量,并就控制测量误差对隧道横向贯通误差的影响值进行了估算。同时对提高洞内控制测量精度提出了自己的建议。
This paper introduces the horizontal control network design, observation and data processing in the Zhongtianshan Tunnel construction, analyses the observation quality of the tunnel control network, and estimates the impact of the control measurement error on the tunnel lateral breakthrough error. At the same time, it gives some suggestion on improving the measurement accuracy inside the tunnel.
