摘要
隧道贯通施工对测量精度要求极高,传统导线测量在复杂地形与长距离掘进中易受遮挡与误差累积影响,难以保障多工作面间的空间对接精度。文章以某隧道工程为研究对象,提出一种融合全球定位系统(global positioning system,GPS)控制测量与精密导线测量的三维空间控制体系,通过建立地面GPS基准网、布设附合导线和洞内精密导线,并实施坐标系统转换与联合平差,实现外部空间坐标向隧道内部的高精度传递。实测结果表明,该融合方案显著提高了测量精度与贯通控制能力,贯通误差优于规范要求,具有良好的工程应用与推广价值。
Tunnel through construction requires high measurement accuracy,and traditional traversing is easily affected by obstruction and error accumulation in complex terrain and long-distance tunneling,making it difficult to guarantee the spatial docking accuracy between multiple working faces.Taking a tunnel project as the research object,this paper proposes a 3D space control system that integrates Global Positioning System(GPS)control measurement and precise traversing.By establishing a ground GPS reference network,arranging connecting traverses and precise traverses in the tunnel,and implementing coordinate system conversion and combined adjustment,the high-precision transmission of external space coordinates to the tunnel interior is realized.The measured results show that the fusion scheme significantly improves the measurement accuracy and through control ability,and the through error is better than the specification requirements,which has good engineering application and promotion value.
