| 中文摘要: |
| 多点后方交会传递坐标和方位角是目前地铁施工测量与监测常用的方法，但在微型盾构施工中采用并不常见，结合南京某电力管线微型盾构施工实践，提出了多点后方交会解决小直径(≤5 m)内坐标和方位传递的问题，并分析了测量精度和提高精度的解决方案，最终在工程实践中取得了满意的结果。 |
| 英文摘要: |
| Multi-point resection transfer coordinates and azimuth are commonly used methods for subway construction measurement and monitoring, but they are not common in micro-shield construction. Combined with the practice of micro-shield construction of a power pipeline in Nanjing, the multi-point resection is proposed to solve the problem of small-diameter(≤5 m)internal coordinate and azimuth transmission. The measurement accuracy and the solution to improve the accuracy are analyzed, and the satisfactory result is obtained in the engineering practice. |
