摘要
复测是所有线路工程都要进行的首要工作,以便核对原有控制点的正确性,并确保在施工过程中,平面和高程放样的精度。因此,对线路工程而言,测量精度和作业效率是衡量线路复测的重要指标。相比于传统的测量手段,GPS具有精度高、作业效率高、不受通视条件影响等优点,所以本文结合GPS技术和兰新线路复测工程进行了一些探讨,得出了相关结论。
In order to check the correctness of the original control points, resurvey is the first job in all of the line project, to make sure the precision of the horizontal and height lofting. So, to the construction project, the precision of survey and the operation efficiency are the important indications to measure the resurvey of the line project. Compared to the traditional measurement, GPS has the following advantages： high precision, high operation efficiency and no influence of visibility conditions. In this paper, we make some discusstion about the resurvey of Lanzhou-Xinjiang Railway, combined with the features of GPS measurements, and the conclusion was given.
