摘要
以贯通误差要求及洞内观测环境为约束条件,从测量过程分析了影响贯通的误差来源,探讨洞内外误差分配及控制方案,提出动态控制洞内误差观点,并以厦门万石山隧道为例实证其可靠性。
Taking through error request and tunnel inner observing environment as constraint condition, having analyzed the source affecting the through error, the paper discussed error assignment and controlling scheme at inner and outer tunnel, put forward the viewpoint of dynamically controlling the error at inner tunnel,and finally the reliability was confirmed by the example of Xiamen Wanshi tunnel.
