由地下导线测量不同布网方案对隧道横向贯通误差影响计算公式,通过模拟计算,对比分析了不同布网方案对横向贯通误差的影响,并且分析了在支导线中加测陀螺方位角定向边的位置、定向精度对横向贯通误差影响关系。
The calculation formula of the influence of different layout schemes on the tunnel transverse penetration error is measured by the underground conductor. Through the simulation calculation, the influence of different layout schemes on the transverse penetration error is analyzed and compared. The position and orientation accuracy affect the horizontal penetration error.
