摘要
分析了各道测量工序对横向贯通误差的影响,并对其引起的横向贯通误差精度进行了估算,设计了可行的测量技术方案,实现了隧道在误差允许范围内的贯通。
The factors of lateral breakthrough error are analyzed by every survey step. The accuracy of lateral breakthrough error is estimated. Finally the appropriate surveying process is designed to ensure the success of tunnel breakthrough within the tolerable range of error.
