摘要
本文按照测量平差的理论，严格推证了地表、地下单导线加测陀螺边对横向贯通精度增益的计算公式，并得到了在计算机上解算的简化、实用算式，利用该算式容易求出陀螺边的最佳配置及其对横向贯通的严密估算结果，它对于地表、地下导线加测陀螺边进行隧道控制的设计和计算具有较大的参考价值。
Based on the theory of leveling error, the calculating formulas for the increment of lateral penetrating accuracy by the layout of ground and underground single guide lines added with spinning top rakes are derived strictly. The simplified and practical calculating formulas which may be solved on computer are also obtained. Applying these formulas, the optimal layout of the spinning top rakes and its strict evaluation results on lateral penetration may be obtained easyly. It is valuable as reference for the design and calculation of tunnel control by the layout of ground and underground guide lines added with the spinning top rakes.
