| 摘 要： | 结合上海地铁二号线东延线广兰路到唐镇站3500m盾构推进施工实践，提出采用GPS与天项仪联合定向测量技术解决工程中遇到的高精度短边定向难题。并通过全站仪和陀螺仪的检测数据进行了对比分析，验证该方法不失为高精度定向测量的好方法。它使得短边定向精度可以达到±2～3”，在实践工作中有一定的借鉴意义。

| Abstract: | Combinating with construction practice of shield promotion of east extension to Shanghai Metro Line II, 3500 meters from Guang Lan Road to Tang Road station, this paper propsing that using joint orientation measurement with GPS and zenith telescope to solve high-precision and short-edge directional problem encountered in engineering. Comparion analysis are made from testing data of total station and gyroscope, verifying that the method is doing well in high-precision targeted measurement. Directional accuracy of short side can achieve ±2-3＂, it has a certain degree of reference in practice. |
